Static equilibrium!
A 25-ft crane supported at its lower end by a pin is elevated by a horizontal cable as shown in the figure. A 250-pound load is suspended from the outer end of the crane. The center of gravity of the crane is 10 feet from the pin, and the crane weighs 200 pounds. What is the tension in the horizontal cable?
I would just like to know if my equations are missing anything. I generally can solve problems of the nature, but the configuration is different than anything I have done thus far and I am not completely clear on the forces that interact with the crane, especially at the pin/wall.
My equations are
∑Fx=Rcos30-T=0
∑Fy=Rsin30-200-250
∑tau=T(25)cos30-(200)(10)sin30-(250)(25)sin30
Are those correct or is my analysis wrong?
