Hi guys, my friend and I are creating a remote control pingpong collecting robot and so far we have the basics to make it move forward and backward; however, I have no clue in how to clean up this mess of the wires flowing from the motors to the remote. Any help is appreciated and I'll include...

any thoughts or direction?

Hi again. So, my teacher has requested that we do an explanation of how this chain works and to some how improve the method. http://home.comcast.net/~p.jectz/bike.jpg There's the basic idea with the force acting downwards and the teeth of the chain pulling. So we could find torque to...

alright thanks got the problem!

I am not sure which formula to use to find the mass of the pulley since the accelartion is a=m2-m1/m1+m2 * gravity that would give me the accel if it was a massless pulley. any help appreciated.

Hi people again, sorry to not have done extensive searching in the forum for a problem like this but I need some help ASAP. By means of a rope whose mass is negligible, two blocks are suspended over a pulley, as the drawing shows. The pulley can be treated as a uniform solid cylindrical disk...

I thought Ft = fT which is impulse and basically what my teacher said is to keep the passanger as safe as possible. which I am having trouble myself for this explanation also, delaying the time will minimize force? I am not sure how that works. Further explanation = how does a seatbelt work...

sorry, I meant the most optimal time to increase time minimizing the force on the person.

Hi guys this is my first post and I need some help with this car saftey project I'm doing in my physics class. I was wondering, hypothetically speaking, if my car design had sensors all around the car that calculated force on impact and it sent it to a computer chip located in the seatbelt...
