I need to find the tension T, γ and β in part 2 of this question.
The question is attached.
First of all, the frame is a right angle triangle because (3L)^2 + (4L)^2 = (5L)^2
take torque about the point O
we got 2LF + mg(4Lcosγ) = Mg(3Lsinγ)
from the balance of force, we got
Tcosβ=(m+M)g + F cos γ
Tsinβ = Fsinγ
The Attempt at a Solution
I have listed these 3 equations but I don't know how to solve them
Please give me some help
