a) What thermal strain does the rod undergo?
b) What is the thermal stress generated in the rod?
2. The ¼" thick 6061?T6 aluminum bar is subjected to a tensile force of P = 5 kips. b = 4"; c = 1.5"; d = 2.5"; and the fillet radii are 1".
a) Determine the maximum stress in the bar.
b) What is the lateral strain in the 1.5" wide section? 5 mm 0.3 m
