UNIVERSITY OF TORONTO Department of Civil Engineering CIV101F S TRUCTURES , M ATERIALS AND D ESIGN (S ECTION E) Problem Set # 4 Assigned: 10-05-2006 Due: 10-11-2006, 10:10 a.m. 1. Member ABC is supported by a pin and bracket at B and by an inextensible cord attached at A and C and passing over a frictionless pulley at D. For the loading shown, determine the tension in the cord and the reaction at B. 2. A slender rod of length L and weight W is held in equilibrium as shown, with one end against a frictionless wall and the other end attached to a cord of length S.

Unformatted text preview: Derive an expression for the distance h in terms of L and S. Show that this position of equilibrium does not exist if S > 2L. **Please turn over for problems 3 and 4** 3. The ramp ABCD is supported by cables at corners C and D. The tension in each of the cables is 810 N. Determine the moment about A of the force exerted by (a) the cable at D, (b) the cable at C. 4. A sign erected on uneven ground is guyed by cables EF and EG. If the force exerted by cable EF at E is 230 N, determine the moment of that force about the line joining points A and D....
