Rotational Motion Part 2

If the force P of magnitude 100N is resolved parallel to the arms AB and AC of the frame, the above figure will be represented as followsComponent of force along AC=100‌cos‌35∘‌N
=100×0.819N=81.9N≈82N
This is the required magnitude of the resolved component along the arm AC.
Compare with given in question, x=82
