Calculate the Young's modulus for the given wire when a load of 2000 N is hung from the wire? The stretched length of the wire is 6.50x103 m and the cross-sectional area of the wire is 1 cm2 and the original length of the wire 4.00 m (a) 1.23 Pa (b) 1.23x 1010 Pa (c) 0.002 x 1010 Pa (d) 1.23x 1012 Pa

Consider a square-faced beam supporting a section of a building. a)  Before installation, the length of the beam is found to be l0 = 15.02 m (figure a). After installation and construction, the length is remeasured and found to be l = 14.98 m (figure b). Determine Young's Modulus Y in N/m2 for the beam if it supports a mass m = 35000 kg and has a side length d = 1.9 m.  b) Suppose that after the beam is installed it needs to be repaired. The weight it supports is removed and replaced with a new mass m2 (figure c). After the new mass is supported, the side length is remeasured and found to be larger with a difference of Δd. Assuming that this side length deformation is uniform and small, write an expression for determining Poisson's ratio v for this beam if its Young's modulus Y is known.

A shearing force of 75 N is applied to an aluminum rod with a length of 10 m, a cross-sectional area of 1.0 x 10-5 m2, and a shear modulus of 25 x 109 N/m2. As a result the rod is sheared through a distance in mm of:

A vertical steel girder with a crosssectional area of 0.15 m2 has a 1550 kg sign hanging from its end. (Ignore the mass of the girder itself.) If the girder is 9.50 m long, how much is it lengthened? Note that the Young's modulus =200x10 9 * O 8.4x10 6m 4.4x10 -6m O 4.8x10 -6m O All answers are wrong

A 16.3 cm long tendon is found to stretch 2.11 mm when a force of 18.8 N is applied to it. If the tendon is round and as an average diameter of 5.13 mm, calculate the Young's modulus of this tendon.
