Question

Problem 2: A 2D general force system acts on the frame, P, = 80 N, P, - 100 N, P, -50 Nm - 200 N-m, and a - 0.1 m, and the frame is in equilibrium. Determine the unknown forces Ax, Ay, and Dy using the equilibrium equations: E. Fix = 0;., Fly = 0; and Moi = 0 where o is an arbitrary point.

use counterclockwise as positive please!!
