a load is suspended by cable from a beam supported by another cable. The angle between the beam and the horizontal is 66 degrees and the angle between supporting cable and the horizontal is 39 degrees.

Part a: what are the angles between the cable supporting the load and the beam and between the cable supporting the beam and the beam?

Part b: what are the 2 equations gotten by newton's 2nd law (using f for horizontal component force at the surface and N for the vertical component force at the surface)?

Part c: what is the torque equation (using L for the length of beam)?

Part d: if the mass of the beam is 200kg and the mass of the load is 1000kg, what are all forces on the beam?
