    This is what i've got so far:

    R(↖): R = 1.5gCos(30) - TSin(20)
    R(↗): F = TCos(20) - 1.5gSin(30)

    Is this correct and if so where do i go next? Thanks.

    FMax = uR at limiting equilibrium.
    u = 1/3
    See what you can do from here.
    Hint: Eliminate either F or R.

    To get F i multiplied R by 1/3 and ended up with...

    1/3(1.5gCos30 - TSin20)

    I then said that 1/3(1.5gCos30 - TSin20) = TCos20 - 1.5gSin30

    Is that correct?
