AI Thread Summary
The project involves building a mousetrap car designed to travel 14 meters up a 5-degree incline. Currently, the car performs well on a flat surface but struggles to exceed 1.5 meters on the incline. The builder is experimenting with a thicker axle to enhance power and is seeking suggestions for improvement. The project must adhere to specific limitations, including size constraints and the use of only mechanical components. The ultimate goal is to create a functioning vehicle that meets the specified requirements.

My project's requirement isn't limited to a mousetrap car but that's what I've built. My car has to go up an incline of 5 degrees. I'm aiming for a distance of 14 meters. My car right now can go on a level surface but can barely pass the 1.5 m on the incline!

My dad is helping me with the project and right now we're going to try to see if a thicker axel will make a difference in its power. Is there any suggestions?

Thanks.

Perhaps it would help if you explained the project, and what it's supposed to do (as well as how you're supposed to accomplish the task). Right now I have no idea what you're doing! :smile:
 
Thanks for offering to help scholzie. :) Although I hadn't reached my desired 14 meters, I've gotten far enough to earn at least a decent grade. Thank you again so much! :)

My purpose was just to build a mechanically powered vehicle that would go up an incline of 5 degrees. Limitations were to fit inside a 60 cm x 60 cm x 60 cm cube, no non mechanical components, and couldn't travel through air.

And how were you using the mouse trap?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
