MEM 230 Drexel University Mechanics of Materials Spring 2010 Problem Set # 2 Due: In class, Thursday, April 15 Problems 1 – 5 are scanned from the Beer, Johnston, DeWolf, and Mazurek textbook (BJDM). Always include free body diagrams in your solutions. 1. Problem 2.16. 2. Problem 2.43. 3. Problem 2.46. 4. Problem 2.60. 5. Problem 2.66. 6. A steel rod having modulus of elasticity E = 29 x 10 6 psi and Poisson’s ratio ν = 0.29 is compressed by an axial force P . Before the load was applied, the diameter of the rod was exactly 2.000 in. In order to provide certain clearances, the diameter of the rod must not

A torque T o with magnitude 75 kip-in is transmitted between two Fanged shafts by means of four 3/4 in. bolts. What is the average shear stress τ ave in each bolt if the diameter d of the bolt circle is 6 in? 1 8. A non-uniform load on a rod AB of length L causes a normal strain along the rod that is expressed as ǫ x = k sin ( π L x ) where k is a constant. Determine the displacement of the midpoint C and the average normal strain in the entire rod. 2...
