Homework Statement
A uniform diving board, of length 5.0 m and mass 52 kg, is supported at two points; one support is located 3.4 m from the end of the board and the second is at 4.6 m from the end (see the figure below). What are the forces acting on the board due to the two supports when a diver of mass 63 kg stands at the end of the board over the water? Assume that these forces are vertical. [Hint: In this problem, consider using two different torque equations about different rotation axes. This may help you determine the directions of the two forces.]
Homework Equations
Torque = Force x Distance
The Attempt at a Solution
There are two pivot points involved. The one that is 3.4m from the diver is going to experience force upward while the support 4.6m away will experience force downward.
I take the weight of the diver*weight of the board*distance from support (3.4m) and come up with a wrong answer. How should I go about solving this?
