Problem 328 | Equilibrium of Force System

Slope instead of angle to define the x- and y-components of force | Equilibrium of Force System

Problem 328
Two weightless bars pinned together as shown in Fig. P-328 support a load of 35 kN. Determine the forces P and F acting respectively along bars AB and AC that maintain equilibrium of pin A.
