A certain wire stretches 0.900 cm when outward forces with magnitude F are applied to each end. The same forces are applied to a wire of the same material but with three times the diameter and three times the length. The second wire stretches O.300 cm O.900 cm O.100 cm O 3.00 cm

A 5.0 x 102 N object is hung from the end of a wire of cross-sectional area 1x106 cm?. The wire stretches from its original length of 200.00 cm to 200.50 cm. What is the stress on the wire? A 5.0 x 10^8 N/m2 (B) 1.0 x 10^8 N/m2 (c) 5.0 x 102 N/m² D 1.0 x 10^6 N/m2

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 cylindrical steel rod is originally 250 cm long and has a diameter of 0.257 cm. A force F is applied longitudinally and the rod stretches 0.910 cm. What is the magnitude of the force? F = N

A steel wire of diameter 1mm can support a tension of 0.2 kN. Determine the diameter of a steel cable to support a tension of 20kN?

A force stretches a (first) wire by 2mm. This wire is made of an unknown material and has a 1.2cm diameter and 3.5cm length. A second wire of the same material has the same length but four times the diameteras the first. How far will it be stretched by the same force?

A force compresses a bone by 1.0 mm. A second bone has the same length but twice the cross-sectional area as the first. By how much would the same force compress this second bone?     0.50 mm     1.0 mm     2.0 mm     4.0 mm     8.0 mm
