[QUOTE="Pushoam, post: 5828865, member: 619344"] [h2]Homework Statement [/h2] [ATTACH=full]209790[/ATTACH] [h2]Homework Equations[/h2][h2]The Attempt at a Solution[/h2] I assume that the wheels are 8ft apart in both x and y direction. Let's denote the length and width of the car by 2l = 8 ft. The torque about an axis connected the contact points of rear wheels : ##\vec \tau = [\{l( \hat x + \hat y) + h \hat z\}\times m( -g \hat z - A \hat x)] \\ = m[ (lg- hA)\hat y + ml ( -g \hat x + A \hat z )## Since the car is rotating along z axis, I take component of torque along y-axis to be 0 and this gives me A = lg/h. But how to make component of torque along x-axis 0? [/QUOTE]
