(d) Centroids (5%)

(e) Center of gravity (5%)

(f) Force couple (5%)

(g)Virtual work (5%)

2. What conditions are required for a three-dimensional rigid body in equilibrium? (10%)

3.如圖一所示(Figure1)
Please find the forces on AB, AC, and BC. The pin and roller supporters are at A and C, respectively. Neglect the weight of all objects (15%)

(a) Please find the equilibrium force for the distributed load and its distance from pin A. (5%)

(b) Plot the free body diagram of T-shaped frame. (5%)

(c) Find the tension force in cable BC and at pin A. (10%)

5.如圖三所示(Figure3)
Determineθand the tension in the spring, which correspond to the equilibrium position of the spring. The unstretched length of spring is h and the constant of the spring is k. The pin and roller supporters are at A and C, respectively. The point load P works on B with the downward direction and neglect the weight of all objects. (20%)
