Question

b=4 PROB. 4-8 4-8. A 3 in.-by-4-in., 0.040-in.-thick, rec- gular brass diaphragm is stretched between a rigid frame made of Invar as shown in the figure. If a drop in temperature of 200°F occurs, determine the resulting normal stresses in the diaphragm. Assume that for the brass E= 16 × 106 psi,G 6 × 106 psi, α-11 X 10-6 in. per inch per degree Fahrenheit, whereas for Invar the coefficient of thermal expansion is zero over the range of the temperature considered.
