Hey guys, I am trying to figure out which motor to order for a side project of mine. I am trying to push a 1000 pound cart up a 10 degree incline. The cart has four elastomer wheels, and may possible encounter carpeted surfaces. I'm not quite sure what to expect in regards to a coefficient of friction yet on a carpeted surface, but I wanted to check my math a bit to understand if I am approaching this problem correctly: Coefficient of Friction = Cf Required Force = Fr Weight = Fw Force Normal to Slope = Fn = = Cf*Fw*Cos(10) Force Parallel to Slope = Fw*Sin(10) So Fr = [Cf*Fw*cos10] + [Fw*Sin(10)]? Thanks for any help in advance! I just wanted to double check if I am doing my statics correctly.
