Question

On a 20 meter diving board hinged at the right end, sticking out over a pool, where would you place a 40kg person so that it had the greatest torque?

Answer: At the farthest point from the hinge.

If the person was placed at the very end, what is the magnitude of force that keeps the diving board in static equilibrium?

Answer: 7840 N

The answers are given, but I would like to know how to get these answers.

Answer 1

Answer #1

Torque= force*perpendicular distance

L=2om IT= 40 x g. 8 = 342 N [m] mz 40 kg at Tosque is maximum the farthest polut T= TXL T= (392728) T= 7040 Nm
