Question

Consider the image shown. Note that the forces in (b) and (d) make an angle of 45° with the wrench. The force in (a) is applied halfway along the length of the wrench. Assume that the wrenches and the magnitude of the force F are identical.

Select the option that correctly orders the magnitudes of the torques exerted on the bolts in (a) through (d) from least to greatest.

1) a < b < d < c

2) a < b = d < c

3) b < d < c < a

4) b = d < a < c
