Repeat Problem 5.13 if a 140-N child sits on the beam at a point one-fourth of the way along the beam from its lower end.

Problem 5.13

A wrench is 50.0 cm long. It is placed on a nut, and a force of 100 N is applied perpendicular to the wrench handle. This force is in the plane of the wrench and nut, at a distance of 30.0 cm from the center of the nut. Determine the size of the torque twisting the nut.
