The weight of the engine is known and so are angles B and C.

I need to determine the tension in the chain AB and the compressive force acting in the spreader bar BC.

What I want to know is:

1. Is it possible to make a force triangle of the system to determine AB? If so how is this done?

2. Is it possible to set up an equation for the horizontal and vertical forces and have BA's x and y components as the variables?

3. Is the compressive force in BC determined in the same way that the tension force in AB is determined?
