A 6-ft-long fishing rod AB is securely anchored in the sand of a beach. After a fish takes the bait, the resulting force in the line is 8.6 lb. Determine the moment about A of the force exerted by the line at B. (Round the final answer to one decimal place.)

Respuesta :

Answer:

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
