Forces of 1000 N, 1500 N, 1000 N and 500 N act at P, Q, R and S respectively with downward direction. The lines of action of these forces make angles of 90°, 60°, 45° and 30° respectively with PS. Find the magnitude, direction and position of the resultant force / Find the magnitude, direction and position of resultant force / Varignon's Theorem in Engineering Mechanics / Mechanics of Civil
