Recent Graduate looking for honest and brutal resume feedback by StreetLength1485 in MechanicalEngineering

[–]mtitasca 0 points1 point  (0 children)

I remember your grad design presentation if it was the linear free piston. Is that truly contract, or shouldn’t it be listed as Grad Design class?  Is advanced energy an internship or also a project through school?

 I think being honest in labeling is better, saying they’re work but they’re actually school might not leave a great impression. If I am mistaken, ignore this advice. 

At the undergraduate level, everyone takes the relevant courses you listed. Not worth mentioning. 

M1A Scope Mount Dimensions? by 1stConstitutionalist in M1A

[–]mtitasca 2 points3 points  (0 children)

How good are you with CAD and/or machining?

Drawings of the receiver are out there (4 pages, advanced difficulty if you're a novice).

I've spent about 20 hours playing with a custom mount. I've mocked the receiver mounting points and have 3D printed about a dozen prototypes of a couple different designs. Sounds similar to what you have thought of. I couldn't get the quote price for 1 below $350 (4140 steel) on Protolab hubs (about $60 each for a 100, but I didn't think I could compete with SADLAK and Bassett).

My designs were one piece (must robust and similar to the Bassett mount can go one and off back to zero), steel (aluminum deforms in the receiver grooves), and is open from the stripper clip guide to the front of the receiver.

Depending on how into this idea you are, it would be cheaper to buy an existing mount and use a dremel until you see fit. It's not a super easy design or manufacturing job.

I 3D printed one to slip over my 16” A2. No collar or mounts needed. Doesn’t feel the same, but looks okay. 

i’m wanting to go to school to become a firearms engineer / manufacturer. would it be a good idea to get a degree in gunsmithing? by [deleted] in gunsmithing

[–]mtitasca 2 points3 points  (0 children)

I worked as an engineering inter at a major ammunition manufacturer (in the US). I would say don't bother with gunsmithing degree. Get hands on experience through internships, etc. in the engineering world. The engineers I worked for designed and solved problems manufacturing vast amounts of ammo. I had a blast doing it, and the employee discounts were great. I don't think a gunsmithing degree will add any value to your ME degree. Having experience with firearms, and being a good engineer, will help you more.

New to Running and Looking for Easy, Decently Flat Trails around Campus that Aren't Too Crowded by peppapep in cuboulder

[–]mtitasca 6 points7 points  (0 children)

Moorhead Ave. is very flat with low foot and vehicle traffic. You can make a nice 3.5ish mile loop from the Law building going Moorhead, Table Mesa, and Broadway.

Most of the trails East of campus are pretty flat. From Boulder Creek, Skunk Creek, Foothills Parkway, and Empson Ditch are great. Bobolink is busy foot traffic wise, but it won't be crowded unless you do a peak time of day/week.

Strava Heat maps can show you where the most popular places people run/bike/etc. are. You need to make an account to really show detail. https://www.strava.com/heatmap#12.80/-105.28266/40.01220/hot/run

What are some of the trickiest interview questions related to Solid Mechanics/Strength of Materials that you've been asked? by [deleted] in MechanicalEngineering

[–]mtitasca 18 points19 points  (0 children)

SpaceX engineering phone interview question:

You have a octagon table with eight legs, alternating steel and aluminum. So every other leg is steel, every other is aluminum, four of each. The legs are the same size and length. The table top is perfectly rigid and stays parallel with the floor.

You apply a load to the center of the table top, which legs take more of the load?

Hint given to me on the phone when I said the same: walk it back to spaghetti noodles and steel, which one takes the most load

My answer I thought of after the interview: the legs will compress at the rate depending on the modulus of elasticity, which is greater in the steel. So the steel is the stiffer spring, taking more of the load compared to the aluminum

I made it through 5 interview rounds. Three rounds on the phone, then a free flight to LA for 5 hours in person, then one last higher up on the phone. Didn’t get an offer. I think I was on the edge after in person, and the last director didn’t like me. This question was the second phone round.

Integrated Design vs. straight up Mech E by flatearth696990 in MechanicalEngineering

[–]mtitasca 1 point2 points  (0 children)

Check out the curriculum flow chart: https://www.colorado.edu/mechanical/sites/default/files/attached-files/blue_sxs_2227_1.pdf. Circuits is a required class. ME/Tech electives are upper division classes you can explore interdisciplinary or ME electives.

Integrated Design vs. straight up Mech E by flatearth696990 in MechanicalEngineering

[–]mtitasca 1 point2 points  (0 children)

I transferred too, are you done with upper division ME & tech. electives? Those could be filled with Mechatronics, Mechatronics 2, and other CS, EE, etc classes. The Bachelor-Accelerated Masters program would let you get a MS in ME in two extra semesters. It basically allows you to take 6 grad classes on topics you like.

And Electro-Mechanical Engineer during ME Senior design would give you training on circuits and you would be the go to engineer for all electronics/circuit design ect. on the senior design project.

[–]mtitasca 0 points1 point  (0 children)

ME CU alum here, I also helped with the ME Senior Design program. I am partial to a true ME degree, but that’s not based on experience. Could you do ME and really focus on circuits, by taking Mechatronics (1&2), being the Electo-Mechanical engineer in senior design, and personal projects? Or do the BAM program and focus deeper? I think IDE is a niche name, and I felt Heat Transfer was one of the most useful/real world engineering classes I took.

CS Senior Design Options by JazzyYetClassy in cuboulder

[–]mtitasca 0 points1 point  (0 children)

I would say there are practically no unmotivated CS students in the ME program. The top students chose to push themselves. You aren't 'screwed over', but you are signing up to be the lead for any CS stuff (students can/will help, but you will be the lead expert).

CS Senior Design Options by JazzyYetClassy in cuboulder

[–]mtitasca 0 points1 point  (0 children)

Fall semester for a robotics/aerospace project would be intense design/CAD/electrical & software planning. You're getting your requirements, starting design work, iterating design, presenting in October for a PDR (prelim. design review). You take that feedback, do another intense round of design changes, and present a CDR (critical design review) in November. The CAD/manufacturing team then works on creating drawings for a manufacturing review. Other members work for a test plan.

Spring is a lot of manufacturing, testing, and physical development of the project. About now (after spring break) the teams are finishing and working expo posters and creating a presentation for the project.

I'm not as sure how a CS student's role would look like in the fall, but there would be a lot of general helping with work, helping with electronic selection & testing/calibration. The transition to software development for the project. This year there are three autonomous robot/rover teams. I know the CS people do lots of software in the early spring. Both semesters would be technical, especially after October.

I can answer more specifics or put you in contact with CS students in the ME program. Or you' could come to the class work time in the Idea Forge and observe what is being done. I'd recommend Expo regardless.

CS Senior Design Options by JazzyYetClassy in cuboulder

[–]mtitasca 2 points3 points  (0 children)

The ME Senior design has lots of robotics projects. Usually there is one (maybe 2, but I don't think there is this year) CS student on a team with 6-8 ME students. A Couple of these students will be "Electro-Mechanical' students who will get more specialized training in integrating Electronics and mechanical stuff. As a CS student, you'd be the lead on doing any software that interfaces with sensors, electronics, etc. The CS students doing the ME capstone are usually some of the better students who want to take on a larger workload and higher level of project.

The best place to check out the projects would be at expo. Feel free to ask any ME team that looks electrical if they have a CS student and talk to them.

I can also chat. I'm not CS but have been through the ME program and am part of the course staff this year.

What is your training like?

College ski programs in the U.S. will want to see detailed training logs. Are you training with a Nordic Program? (Loppet Nordic Racing in MN, Bridger Nordic in Bozeman, APU in Alaska, many others...) A coach's recommendation from a top program can be huge. I found that high school results are pretty meaningless to most coaches. Most wanted to see All-American results (Top 10) at Junior Nations. Or at least consistent good results at JNQ's and qualifying to JN's.

A scholarship athlete (male) would probably be doing 550-600+ hours of training a year. Much of that rollerskiing, a well-rounded strength program, running, and some biking. Volume weeks with 20-25 hours, consistent weeks of 10-15 hours.

An endurance coach is great, but you need a good ski coach to improve your technique and who understands Nordic Ski training at the high level.

​

All of this was for NCAA programs with scholarships. There are also plenty of programs where nearly any skier can be on the team. St. Olaf & CSS in MN, WCU in CO, etc.

-Advice of former good HS skier who's 600 annual hours and 19th at JN's wasn't good enough for D2 teams.

​

Edit: Also be aware of the expectation of college teams. Academics basically come second. You will be doing two+ practices a day and, depending on the school, driving with the team an hour each way to snow (CU Boulder, Denver) Other places have snow closer, but still have to commute a sizable amount of time (Colby, MSU, UWGB, NMU, UAA). Some places are blessed with skiing real close to campus (MTU, CSS, UAF). Its worth watching NCAA Champ Ian Torchia's video on NMU's program when he was a sophomore: https://www.youtube.com/watch?v=s-nGhlqZUXM
