Question

A 2.00-m-long diving board of mass 12.0 kg is 3.00 m above the water. It has two attachments holding it in place. One is located at the very back end of the board, and the other is 25.0 cm away from that end.

1-Assuming that the board has uniform density, find the forces acting on each attachment (take the downward direction to be positive).

2-If a diver of mass 65.0 kg is standing on the front end, what are the forces acting on the two attachments?
