Final Exam ( ) ID#: _____________________________________ Circle on this test sheet your choice of correct or nearest item on the list for each of the following: 1. A 4-ft concrete post is reinforced by four steel bars, each of 0.75-in. diameter. It is known that E s = 29 × 10 6 psi, α s = 6.5 × 10 6 /°F, E c = 3.6 × 10 6 psi, and c = 5.5 × 10 6 /°F. If the tensile stress developed in the concrete due to thermal expansion is known to be 50 psi, the temperature rise T is ( a ) 74.6°F. ( b ) 76.1°F. ( c ) 77.6°F. ( d ) 79.1°F. ( e ) 80.6°F. ( f ) 82.1°F. ( g ) 83.6°F. ( h ) 85.1°F. Fig. P1 and P2 Fig. P3 and P4 Fig. P5 2. Refer to Problem 1. The change in length δ post of the post is ( a ) 0.0228 in. ( b ) 0.0224 in. ( c ) 0.0220 in. ( d ) 0.0216 in. ( e ) 0.0212 in. ( f ) 0.0208 in. ( g ) 0.0204 in. 3. The horizontal shaft AD is attached to a fixed base at D and is subjected to the torques as shown, where 650 lb ft A T = and 700 lb ft. B T = A 2-in.-diameter hole has been drilled into portion CD of the shaft. If the entire shaft is made of steel for which 6 11.2 10 psi
