    1. The problem statement, all variables and given/known data

    The link above have the full problem
    I mostly have issue with Part (b) of the problem where am not familiar with and don't know how to solve that part. I was wondering if someone can put some light in the tunnel or provide a link where I can study about this type of problems

    As for Part (a) I attempted it and although came really close to the solution is not what am asked to prove so I was wondering if someone can spot any problem with my calculation there

    2. Relevant equations

    M = P*L1 = P*R*sinθ
    T = P*L2 = P*R*(1-cosθ)

    3. The attempt at a solution

    This is my attemp and what method I used for it

    Show me how you derived the expression for T .

    I am not sure I understood correctly what you are looking for but I included both what T is = to and its derived version
