A 145 lb diver stands at the end of a rigid 7 ft long diving board. What is the magnitude of the torque the diver exerts on the diving board

Torque = 1015 ft.lb

Explanation:

Torque is defined as the turning effect of force. It is the force that can cause an object to rotate and gain some angular acceleration. Torque is basically an angular analog of force. The method to calculate torque is simple. Take the perpendicular distance from the line of action of force to the axis of rotation. Multiply this distance with the magnitude of force. The magnitude of this product gives the torque. Therefore,

Torque = (Force)(Perpendicular Distance)

Since, the diver is standing at the end of diving board.

Therefore,

Perpendicular Distance = 7 ft

Force = 145 lb

Therefore,

Torque = (145 lb)(7 ft)

Torque = 1015 ft.lb

hey , the answer is c

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
