Homework Statement
A uniform beam is supported at its centre of gravity. The forces, F, 4N and 6N act to keep the beam in equilibrium. Forces 4N and 6N are acting at 60deg to the horizontal, calculate the force F, if the beam remains in equilibrium.
F is acting upwards on the left of the beam with 4N at 60deg downwards. 6N is on the right acting at 60deg downwards.
Homework Equations
Now we know the physics teacher got this wrong and the answer to F will actually be a negative acting downwards from the top.
The Attempt at a Solution
I don't know where to start could someone outline the working for a solution?
