Question

Given the vector from the pivot point to the force and the magnitude of the force.
1.How would one find the angle of the force?
2.How would one find the torque?
3.How would one calculate the maximum/minimum torque?

Answer 1

Torque is F x R, where x denotes a cross product vector.
Depending upon the angle between the vectors, the maximum torque is F*R and the minimum toque is zero.
