Static Equilibrium of pedestals

[G-reg]

Homework Statement

A diver of weight 730 N stands at the end of a diving board of length L = 5 m and negligible mass. The board is fixed to two pedestals separated by distance d = 1.5 m.

What are the magnitude and direction of the force on the board from the left pedestal? (Include the sign. Take upward to be positive.)

Homework Equations

I think that it's this..

sum of forces in the y direction = 0

force of left pedestal = Fl
force of right pedestal = Fr
force of diver = mg = 730N

The Attempt at a Solution

-Fl + Fr - mg = 0
3.5Fr(mg) - (0)mg = 5Fl(mg)

is this on the right track?

Looks good! You have 2 equations with 2 unknowns so you can find the answer.
