Moment of Force, M = 51.6 lbf-ft

Explanation:

Given,

The fishing rod AB of length, L = 6 ft

The force acting on the rod, F = 8.6 lbf

The moment of force about A is given as the product of force and perpendicular distance. It is given by the formula

M = F x L

Substituting the given values in the above equation

M = 8.6 lbf x 6 ft

= 51.6 lbf-ft

The moment about A of the force exerted by the line at B is, M = 51.6 lbf-ft
