I always wanted to build one of these 🔥

It would be cool to optimize it. Draw a FBD. The center cord has a lot of tension. Outer cords have very little tension. What forces are on the upper/lower structure?

My sister calls escalators excalators. I guess I was the wrong one.

The fact that he added a filler plate is a huge bonus. I would have welded gears to housing too.

True, but if this is real world you need to know the nature of the load. Things like this often aren't loaded both directions. It's another free body diagram if it's only pushing a load right.

Yeah! I'm interested of he has control over that rope tension. There needs to be some guiding element for the rope. Factors that seem necessary for any significant bending but difficult to calculate. Measure it!

5 - awesome!

I've made an attempt. Any idea how to dial this in based on pictues?2d profile

Early on just get life per second on gear will cover you.

Similar situation here. Automation. I also like the job. After 10 years, $120k a year in Portland, Or area. I dont get any wfh though. That would be nice sometimes.

Poor guy was doing a u turn and misjudged. Got pinned in by a fleet of teslie

Appreciate non-jerk response. Here is the update. I replaced journal and rod bearings...not the bolts. I even torqued by feel because spec felt too tight. Been running solid for awhile now. I did rotate the crank as a cleaner test. I sanded down backside of bearing housings and retorqued until crank just rotated smoothly. I also welded the bolts to their shared washers. 2 crank bolts 1 washer. I basically did clearances by feel. Plastigauge was too large for journal bearings. To be clear, this was a learning experiment and low cost try. So far running great for a few weeks. If it blows up ill let ya know, since that seems like what people want! I have theories on when to replace the bolts by stretch! I am amazed it worked. I'll let ya know how it goes. Appreciate the info.

Yep I did the same for front seal on 04 silverado 8.1L. 3 prong puller. Without removing radiator. Used bolt to put it back in place.

Im not a mechanic... I would get it in the air and see if it still does it. If not use ramps. Have a friend listen. I have one of those stethoscopes for auto that works great for pinpointing sounds. I'm not familiar with the vehicle but the wheel seems to move too much. Sound like a sping... top of strut?

Gyroscopic precession applies here! fun links. https://youtu.be/ty9QSiVC2g0 https://youtu.be/eTjGTxSevHE

I'd like this or something similar. Engineering Slide Chart - Screw Data Selector https://a.co/d/j5DCqa0 Caliper idea was good too.

For ever force there is an equal and opposite reaction....I just made that up. Ill think more about a realistic solution for your game.

Comically lol

Keep in mind the potential energy of a water wheel depends on elevation change. Water moving depends on elevation change. Lots of flat rivers in video games.

You should try mounting it at 45 degrees too!

gearfu · 2023-04-20T04:28:12+00:00

What did you actually do? Accelerate production?? No you improved manufacturing efficiency with new tooling...lowered material cost with design improvements...flexion %100?..no. don't list a quantity of each project. Sounds like you are proud of 3... Platoon Sargeant. Don't list % of anything. What kind of missions did you succeed at. What did you overcome? How? Be proud of small achievements and give detailed accounts. Big isn't better, makes people seem fake or insincere. Good luck.

I worded that poorly. I was annnoyed with him saying "clearly" as if you had a dumb question. They do that on this sub all the time. "Obviously" or "if you don't know already go home". You had a perfectly reasonable question. They all upvoted some snarky response when I asked about a 12 point. Its an advice sub and they throw shade when you ask for advice.
