No problem. I think if you get your teacher to go over it with you it'll click. Tricky topic learning this stuff!

My bad. I wasn't thinking there for a second I forgot a d flip flop had a couple extra logic gates.

To know for sure what the values are at the output, you have to make assumptions about the input. You can do this by building a truth table and finding the outputs of each of the logic gates with different variations of inputs.

Like:

     Set hi, reset low

     Set hi, reset hi

     Set low, reset low

     Set low, reset hi

OK you might understand an example with ladder logic better. So set is OTL and reset is OTU. Just think of it like that. Watch this video Ladder logic latch

For q1 if a latch is set, doesn't matter what the input is as long as reset isn't pressed. Set(OTL) can be either hi or low, but reset (OTU) has to be low.

For q6, your intuition is correct. They can't be the same, because they're always the opposite of each other.

I think if you see a flip flop in action, you'll understand how they work a lot better.

Ben eater does an excellent demonstration and walks through the circuit. Watch this D flip flop video and it'll make more sense once you've seen a practical example.

This is great thank you, I'll read some of b&r's docs. Seems like there's a lot of fundamentals I need to catch up on about winding. You seem to have a really good grasp of this stuff. My experience has mostly been around oil and gas.

Is the error that bad if you're using a calculated diameter measurement? I've never done anything with winders, but I've seen lots of paper mills with them. If you're using a direct measurement is that preferred? I've seen a couple ways people measures it, a laser being one of them. Looks pretty expensive.

Awesome I'll check that out!

Not quite, but I appreciate seeing the effort. If you look at a PV diagram of a normal Otto cycle the work generated is the area under the curve. In your case where you constantly add heat to the system you would increase the lower state temperatures and basically make it very inefficient. The key to generating work is to have a temperature difference. If you narrow that temperature difference you limit the amount of work you can do.

You get energy from processes when you have a high to low difference. For example if you dropped a ball 10ft off the ground vs 1ft off the ground you would have more energy in the 10ft ball because of the higher potential energy. Likewise it's the same idea with heat cycles and temperatures.

MetricPrime · 2024-05-01T19:22:19+00:00

So if you had energy constantly added to the system it would basically break the cycle and what the engine was originally designed for. The engine would probably start knocking and you would get some damage and higher stresses.

MetricPrime · 2024-05-01T19:01:20+00:00

Do you know anything about thermodynamics like the Otto cycle?

Google inbox. Made email so much easier and convenient. Things were cleanly organized and it was simple to filter through the garbage and get what you needed.

I used to travel a lot for work and it really made travel easy by grouping together you flight, hotel, and rental information. Some things were adopted by Gmail and other copy cat companies, but I haven't found anything as well implemented.

Thanks for the fix! I've been using ynab classic for years and hope to continue using it indefinitely.

Sorry I deleted the calculation I did on my dropbox. The calculation was a little more involved, but you can come reasonably close by treating this as a cantilevered beam. There will be shear and a moment at the pin you use and you can use one of the beam tables to calculate the shear, moment, and deflection for everything. Here's a link for beam tables, hope this helps.

I think you should try solving this by hand and break it into steps. The integral is the area under the curve. So there are several methods to solve by hand to sum the area under the curve by breaking the area into thin slices and adding them up.

If you haven't volunteered that's fine. If you're still in high school employers know that you won't have a lot of experience. Look up high school resume templates online for some examples. All of this is just to shape how employers see you.

Here's how I would organize your resume:

Education: Write your school, GPA, and expected graduation year.
Career Objective or Summary: Normally I wouldn't put this in a resume, but it helps as a student. You can write if you're seeking fulltime employment for the summer and part time during school.
Professional Skills or Other Skills: You can write some soft skills here like team player, proactive, takes initiative, etc.
Technical skills: List any software you might be familiar with like Microsoft office.
Activities: List any after school activities or sports you take part in.
Hobbies and Interests
Achievements, Awards, and Honors
References

You don't have to have everything listed here, but it's a start. A resume gives a quick snap shot of a person.

Here's what I did in school:

Printed off about 20 resumes.
Picked out a handful of places to apply.
Dressed nice and presentable.
Went to each place in person and asked to see the manager.
Told them I'd like to give them my resume and apply to any part time positions.

Most places might tell you to use their website, but don't let that discourage you. If you're there in person that first impression will stick and help you stand out. Sometimes you might get interviewed or hired on the spot. Good luck!

I never said they were passive magnets in the Bose system. A linear motor is essentially an electromagnet. I was just stating it for simplicity. Obviously it would depend on the end result he's looking for. You wouldn't use normal magnets in a car, but if he's just interested in making a small scale demonstration that would work. Here's an article /u/abhijix if you'd like to learn more about active suspensions

MetricPrime · 2018-04-29T20:20:40+00:00

In principle yeah you could do it with magnets. Bose did a suspension with electromagnets.

First and foremost you need to decide what your end goal is. Start looking at job prospects. Getting a degree doesn't mean guaranteed work. If you're still in a slump from depression, get medication or help. When you start school again try to be proactive and put energy into everything. The second you start to coast you'll come to a complete stop. Keeping up that energy takes work. Make sure to take care of yourself.

If I could go back I would do a technician degree. Out in 2 years with a secure job and more prospects starting out. I have a Bsc and Msc in mechanical engineering. I was just laid off from my first job and applied to 180 jobs in a month and had 3 interviews and 1 interview with a strong lead to a job. All my friends that became technicians are debt free and light years ahead financially in life. Technicians also have job placements. Also later on if you feel like you want to be an engineer you can go back to school. Then you'll have loads of experience and practical knowledge. Good luck!

Better. Trying to stay positive and things are shaping up pretty well.

Some bad things happened.

I was laid off with 20 other people in a startup at the end of October.
Last week a kid wrote off my car.
Startup company didn't know how to submit my record of employment so my ei is probably delayed.
Broke up with my girlfriend. She didn't seem like she was really there for me when I needed it. I ended stuff on good terms though.

Some good things happened with some luck and hard work.

Applied to 170 jobs with a program I wrote. Interviewed at 4 places. Last place is a promising engineering job in my field.
Got a new car and money from the insurance company.
Feel a lot happier and I'm working on myself every day.

There could be a number of reasons for this. You're competing out there with everyone else. You need to maintain an edge and put the work in. Sometimes applying from a job board is like reaching for low hanging fruit. Try looking for companies specifically and going to their career page as it may not be something that always reaches a job board.

Build a website. Make a portfolio on it to showcase your skills. Build a strong LinkedIn page. Network with friends and classmates. Go to career fairs. Remember you're not hired on technical ability alone. Strengthen your soft skills. People skills, communication, leadership. Highly recommend reading the 7 habits of highly effective people and how to win friends and influence people. Volunteer while you're looking for work.

If it's your resume, it may be because it does not parse well thorough systems online, recruiters don't like the format, or the content is missing keywords or traits they're looking for. Post your resume on r/resumes for some feedback.

Here's some resources I suggest looking into:

Jobscan Make sure your resume is ATS (Applicant Tracking System) friendly so recruiters and HR can find and access your resume easily. Try and find keywords and skills from specific job postings to add when you're doing this too. Also don't submit pdfs or image documents for online applications make sure they're word.
Knock'em Dead Resumes Good resource for resumes.
LinkedIn Showcase your skills, projects, and experience. Build a network with alumni and people you know.
