A hollow, circular, cast-iron pipe (E, = 12,000 ksi) supports a brass rod (E, = 14,000 ksi) and weight W = 1.5 kips, as shown. The outside diameter of the pipe is d. = 6 in. (Assume the weight density of brass is 520 Ib/ft.) Nut and washer (d, = in.) Steel cap (1, = 1 in.) Cast iron pipe (d = 6 in., t) L,= 3.5 ft L. = 4 ft Brass rod (4,= in.) W h s the minimum required wall thickness t. min (in inches)? (Include the weights of the rod and (a) If the allowable compressive stress in the pipe is 15,000 psi and the allowable shortening of the pipe is 0.06 in., what steel cap in your calculations.) 0.005 x in. (b) What is the elongation of the brass rod 8, (in inches) due to both load W and its own weight? (Use the deformation sign convention.) 0.0229 v in. (c) What is the minimum required clearance h (in inches)? 0.0829 in.

Problem 3 (20 minutes) The bars' assembly has the dimensions, diameters and materials indicated (EST 29,000 ksi; EBR = 15,000 ksi). The assembly is fixed at one end and has D in, E = 1. 10 in and F20 kip. Determine the normal force N in the bronze and the steel = d=2in = 30 d= 1 in F(kip) BRONZE ← STEEL A B ↑ c D(in) Elin 2. Draw the normal force diagram along the assembly 3. Determine the elongations ALAB (of portion AB), ALBC (of portion BC) and ALAC

The prismatic rod shown is made of a steel that is assumed to be elastoplastic with E = 200 GPa and oy = 280 MPa. Knowing that couples M and M' of moment 525 N·m are applied and main- tained about axes parallel to the y axis, determine (a) the thick- ness of the elastic core, (b) the radius of curvature of the bar. y M 18 mm 24 mm X 'M'

A compound bar consisting of bronze, aluminum, and steel segments is loaded axially as shown in the figure. Determine the maximum allowable value of P if the change in length of the bar is limited to 2 mm and the working stresses prescribed in the table are not to be exceeded. E=200 GPa A=D300mm?
