5:37 PM 53% ubian.ub.edu.ph/student 10 2 14 University of Batangas Fill in the blanks: Q1. The rigid bar ABCD of negligible weight is initially horizontal, and the steel rods attached at A and C are stress-free. The 20-kip load is then applied and the temperature of the steel rods is changed by AT. Find AT for which the stresses in the two steel rods will be equal. Use a = 6.5 x 10-6F and E = 29 x 10° psi for steel. A = 0.5 in.? 3 ft 94 |20 kips 4 ft 4 ft 2 ft - 2 ft A = 0.75 in.? ANS : ΔΤ= °F (WN-whole number) ( Previous Continue > Status II

Determine the inner and outer diameter of the hollow shaft which will replace a 76 mm solid shaft made of the same material. The hollow shaft should be as strong in torsion but it weighs only half as much as the solid. ANS: Do = || mm, Dj = mm (Whole Number) ( Previous Continue > II
