Answer:
F1 = 140.2[N]; F2 = 61.72[N]
Explanation:
To solve this problem, we must make a free body diagram, with the different forces and distances that apply on the Daredevil and its bar.
In the attached image is a free body diagram, with the different forces and distances that are on the equilibrium bar.
First, we performed a sum of forces at y-axis equal to zero, in this way we deduced one of the equations for the forces of the arms F1 & F2. It takes another equation, to find each of the forces.
Then we do a sum of moments equal to zero, at the point of force F1, in this way we can find an equation for Force F2. With the force F2 we replace in the first equation and we can find the force F1.
In this way the forces are:
F1 = 140.2[N]
F2 = 61.72[N]
In the attached image we can see the equations developed to find the forces F1 & F2
