Question

ire of initial length Sa is run over a frictionless pulley as shown. The weight W causes the ire to stretch by amount A. For a- 1.3 m and A-7 mm, the average normal strain in the wire is best given by 2690 x 10 380 x 10 e. 2390 x 10 1790 x 10 DA 13 29 7. A 0.5-in diameter test specimen of gage length 2 in is subject to the tension test data shown below. For P*-11 kip, and 3.4x 103 in, the material's modulus ofelasticity is best given by 65.9 x 10 psi L 2 P Fra b) 33.0 x 10 psi 8.24 x 10 psi d. 3.24 x 10 psi 836 8. For the data of Problem 7, the material's modulus of toughness s best given by a. 952 psi 6238 psi 59.5 psi d.) 47.6 psi
