How Do I Analyze Compressive Stress in a Crane Jib?

[ArronJames]

im am a first year mech eng student. I am so lost on this question. the image is the diagram I am trying to solve. i think the compressive stress of the crane boom is what is confusing me. i don't want the answer, just where do i start? Force polygon? math?

please tell me how you would solve this. thankyou

Is this your first year as a freshmen with no statics under your belt? Or have you already taken the core engineering science and Physics courses? If the latter, sum moments about one of the supports = 0. Each member is a 2-force member...the wire in tension and the jib in compression, with their forces directed axially along the axis of the member. Don't forget sum of Fx = 0 and sum of Fy =0.
