Stuck on part b?
I found the angle between the floor and the beam to be about #34.69# degrees and the angle between the beam and weight to be about #55.31# degrees. Lastly, the magnitude of #vecP# to be #125.81N#
I found the angle between the floor and the beam to be about

In the above figure forces acting on the beam at different points at a given moment of its lift have been shown.
Here
and
Resolved parts of the applied force
Considering considering the moments of the forces about point
Now considering the equilibrium of vertical forces we get the reactionary force
Again considering the equilibrium of horizontal forces we get the frictional force (
