Homework Statement

[/B]
Determine the maximum load G [N] placed on the incline of an angle α, to ensure the
equilibrium of the system shown. The beam of length (a + b) is weightless and the
friction coefficient μ is only between the load G and the incline.

Hi mohdapadela, Welcome to Physics Forums.

I suggest that you start by analyzing the force P and lever ab to determine another expression for the tension in the rope. For the system to be in equilibrium the tension provided by lever must balance the tension produced by the load.

It would be preferable if you would type in your equations and provide some description of what you are trying to accomplish at each step. It is very difficult for helpers to comment on details of your work when it is in an image.

Especially blurry images which aren't rotated so you can read them.
