# Thread: Mechanics M1 Friction HELP

1. ## Mechanics M1 Friction HELP

A particle is in equilibrium under action of three coplanar forces whose magnitudes and directions are shown in the diagram. Find values of P and Q.

Sorry I dont know how to draw so Ive attatched it as a word document (p.s could someone tell me how)

Sorry.

2. $\sum F_x = 0$

$4 - Q\cos(20) = 0$

$\sum F_y = 0$

$Q\sin(20) - P = 0$

can you determine Q and P now?
