the two conditions of equilibrium are:
Sum of vertical and horizontal forces is zero.
Sum of moments about any point is zero.
Without knowing how the rope is attached, I can't do more. But here are some similar moment related problems that might help you understand.
Try this one: https://www.youtube.com/watch?v=EzLnvCJxW54
A hungry bear weighs 700 N walks to a basket of candy that is located in
end of a beam . The beam is uniform and weighs 200N , with a length of 6.0 m . The beam is supported
by a cord forming an angle of 60 ° . The basket weighs 80 N. When the bear is within 1.2 m
determine the tension of the rope.
I know the bear and the bear are affected by the mass- gravity force and the normal, the cord is affected by the tension and the mass- gravity force, but i really don't know how to start it.
any help will be appreciated
