    Cool [SOLVED] Resolving Forces - Mechanics

    Hi, kindly have a look at the attached image.

    For part (ii) I have drawn the vertical and horizontal components, I just don't know where to put the 40 degree angle, at the head or at the tail and why?

    Thanks!

    P makes 40 degrees with the inclined plane.
    So Pcos(θ) is along the inclined plane and Psin(θ) is normal to the inclined plane.
