Attached to one end of a vertical wall is a 1220N uniform beam that is held up by a cable at the other end. At the far end of the beam hangs a 1960N crate. Using the attached image, please answer the following questions:

Why is the direction of F_v facing up instead of down?
where should the pivot point be placed in the image below?
If the length of the beam is L, what's the distance from the pivot to where the 1220N weight is hanging? and the length to where F_T and the 1960N weight is?
In order to find torques, What is the angle between F_T and the beam? What is the angle between the weights and the beam?
Find the tension force.
Since you now know the tension force, find the forces F_Vand F_H using Newton's 2nd law.
