"If the car was going slightly downhill with the end result that speed was constant while coasting, then the net torques on the tires and on the drive shaft would be zero."
Great! That is what I want to know. Thank you very much.
But if I put my finger into the center of the wheel, the wheel...
"There could be equal and opposing torques on that object that cancel out, resulting in a net torque of zero."
Could you please rephrase this sentence? If there is no net torque, how can I calculate the equal and opposing torques?
Hi everyone,
A question just pop up from my head.
Imagine a rigid body cylinder is rotating freely about its z-axis with a known angular velocity. Let's say the whole system is frictionless. How can I get the value of the torque at the center of the z-axis?
Is the net force on this...
