Statics & Strength of Materials
1. In the structure shown member AB is pinned at the floor, and member CB is a cable pinned at the wall. Determine the values of the external support reactions, and the force in member CB. (Ax = -78.3 lb., Ay = +178 lb., C = 455 lb., CB = 455 lb. (T))
2. The structure shown is composed of members ACD and BC pinned
together at point C.. The structure is pinned to ceiling at points A and B. Determine the
values of the external support reactions, and the force in member BC.
(Ax = 0 lb., Ay = -1600 lb., By = 5600 lb., BC = 5600 lb.T)
3. The structure shown is composed of solid rigid members ABC, CD, and BDE
pinned together at points B, C, and D. The structure is supported by a roller at point E,
and pinned to the wall at point A.For the structure shown, determine the values of the
external support reactions, and the force in member DC. (Ax = 8,670 lb., Ay = 10,000 lb.,
Ex =- 8,670 lb., DC = 15,600 (T))
4. The structure shown is composed of solid rigid members ABC, CD,
BD, and DE pinned together at points B, C, and D. The structure is pinned to the floor at
points A and E. For the structure shown, determine the values of the external support
reactions, and the force in member CD. (Ax = 6375 lb., Ay = 10500 lb., E = 10,625 lb.
CD = 9000 lb. C)
5. The structure shown is composed of solid rigid members AB and BC
pinned together at point B. The structure is pinned to the floor at points A and C.
Determine the values of the external support reactions
(Ax = +419 lb., Ay = 4170 lb.
Cx = - 5419 lb., Cy = 15,830 lb.)
