    Solving 2D moments about point O

    yes we are so would it be -300sin60 + 300 cos 60 - 50 + xsin30 - x cos 30

    Solving 2D moments about point O

    how? if force has continuing line of action shouldn't we measure along the yaxis which would be like i did?

    Solving 2D moments about point O

    Sorry I am really having trouble understanding the concept... wouldnt 0-G be 300sin60 and c-f be 50 + xsin30

    Solving 2D moments about point O

    thanx so is this correct so far -15 KN-m = F[-(sin30°)-(50mm)-(300sin60°)]

    Solving 2D moments about point O

    (a) The moment the force, F, makes about O is 15 N-m clockwise, and θ = 30˚, find the magnitude of F. (b) If the force F = 100 N, determine the angle θ so the force develops a clockwise moment about point O of 20 N-m. Limit your answers to a range of 0º ≤ θ ≤ 90º. I'm a little lost can...
