Given information
We are given that:
The mass of the uniform beam is .
Step-by-step explanation
Step 1.
The beam is in equilibrium, so both the net torque and net force on it must be zero. From the free-body diagram,
Calculate the net torque about the center of the left support, with counterclockwise torques as positive. Calculate the net force, with upward as positive. Use those two equations to find and .
