Homework Statement
A uniform diving board of mass=27kg and length x=4.3m is supported by two beams. beam A at x=0m and beam B at x=1.1m. A 68kg diver stands at the other side of the board.
A. Find force on support A.
B. Find force on support B.
Homework Equations
Net force = 0
Net torque = 0
md=68kg -mass of diver
mb=27kg - mass of board
l = 4.3m - length of board
The Attempt at a Solution
I am just having a lot of trouble figuring out the forces and toques for these static equilibrium problems. So I set my ForceNet = 0 = md*g + mb*g - FA - FB. (Not sure if this is correct)
TorqueNet = md*g*l + mb*g*(l/2) - FA*(0)? - FB*1.1
So I guess I don't understand what to use as my pivot point because this torque equation gets rid of my FA all together.
Thanks!
