Homework Statement
Im doing Physics 12 with equilibrium
The diagram shows a beam 3.2 m long with masses hanging from it. The mass of the beam is negligible in comparison with the other masses.
Diagram:

a.) If the beam is in equilibrium, what is the force of tension in the cable?
b.) If the beam is in equilibrium with the 150kg mass 3.2 m from the 90 kg mass, how far is the 90kg mass from the cable?
c.) If the force of tension in the cable is 2352 N and the cable is attached 2.2 m from the right end of the beam, what is the net torque on the beam about the right end?
d.) If the force of tension in the cable is 2352 N and the cable is attached 2.2 m from the right end of the beam, what is the torque about the point where the cable is attached to the beam?
Homework Equations
Net Torque = 0
Net Fx = 0
Net Fy = 0
Torque = Force x length
Torque = mass x gravity x length
The Attempt at a Solution
There were many similar examples but not in this design. So I am unsure if I am doing it right.
If you could at least answer question part a
I would greatly appreciate it
Thanks
