Problem 316
Determine the values of α and θ so that the forces shown in Fig. P-316 will be in equilibrium.
Problem 315
The 300-lb force and the 400-lb force shown in Fig. P-315 are to be held in equilibrium by a third force F acting at an unknown angle θ with the horizontal. Determine the values of F and θ.
Problem 314
The five forces shown in Fig. P-314 are in equilibrium. Compute the values of P and F.
Problem 313
Figure P-313 represents the concurrent force system acting at a joint of a bridge truss. Determine the value of P and E to maintain equilibrium of the forces.
Problem 312
Determine the magnitude of P and F necessary to keep the concurrent force system in Fig. P-312 in equilibrium.
In static, a body is said to be in equilibrium when the force system acting upon it has a zero resultant.
The sum of all forces in the x-direction or horizontal is zero.
The sum of all forces in the y-direction or vertical is zero.
