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.

•  b=d<a<c

•  a<b=d<c

•  b<d<c<a

•  a<b<d<c

Answer 1

Torque, T = r x F = r F sin(theta)

Correct order would be:

A < B = D < C
