, where r is the perpendicular distance, F is the force, and θ is the angle between the Force and the position vector, r.
𝜏1 = (L/4)(2F)sin(90°) = 0.5LF
Six forces, each of magnitude either F or 2F, are applied to a door as seen from above in Figure P7.6.
Rank, in order, from smallest to largest, the six torques T1 to T6 about the hinge.
