For the truss shown below, compute the horizontal and vertical components of displacement of joint B produced by the 100-kip load using the Virtual Work Method. Joint E is supported by a roller and Joint D is support by a pin. The area of all bars = 4 in² and E= 24,000 kips/in². A 20' B E 8 20' D P=100 kips in 15' 15'
