Two forces 50N and 100 N are acting on a rod capable of rotating it about O as shown in Fig. What is the net torque acting on the rod ?

Fig shows three forces F_(1), F_(2) and F_(3) acting on a rod pivoted at its end. Find the torque of each force about pivot.

A 100 N uniforms rod of length 6I is supported by two forces F_1 and F_2 as shown here. What is the ratio for F_1 to F_2 ?

A force vec F = 2 hat i + 3 hat j N is applied to an object that is pivoted about a fixed axle aligned along the z coordinate axis. If the force is applied at the point vec r = 4 hat i + 5 hat j m , (a) the magnitude of the net torque about the z and (b) the direction of the torque vector tau .
