Q1: Find the horizontal deflection of point B for the structure shown in Fig (1). Figure (1)

2.19 Both portions of the rod ABC are made of an aluminum for which E = 70 GPa. Knowing that the magnitude of P is 4 kN, determine (a) the value of Q so that the deflection at A is zero, (b) the cor- responding deflection of B. A 20-mm diameter 0.4 m B 0.5 m 60-mm diameter C Fig. P2.19 and P2.20

A truss is pinned at joint C and is simply supported at joint A, as shown in Fig. 2a. Each member of the truss is made of A-36 steel and has a diameter of 20 mm. Using Conservation of Energy Method, find the vertical deflection of joint D. 4 m 3 m B 3 m 20 kN Fig. 2a

Q. Determine the slope at the supports of the beam shown in Fig. I using the double integration method. Also, determine the maximum deflection. El is constant. E = 29,000 ksi and I = 3,500 in.4. 2 k/ft ↓ ↓ ↓ ↓ ↓ Fig. 1 A C B -15 ft- -6 ft-
