Example I: Consider a cylindrical specimen of a steel alloy 10 mm in diameter and 75 mm long that in pulled in tension. Determine the engineering stress. Also, determine its elongation when a load of 23500 N is applied. The engineering strain is 0.0013. Example 2: For a brass alloy, the stress at which plastic deformation begins is 345 MPa (50,000 psi), and the modulus of clasticity is 103 GPa (15 x 10" psi). (a) What is the maximum load that may be applied to a specimen with a cross- sectional area of 130 mm' (0.2 in.") without plastic deformation? (b) If the original specimen length is 76 mm (3.0 in.), what is the maximum length to which it may be stretched without causing plastic deformation?

During heavy lifting, a disk between spinal vertebrae is subjected to a 5000-N compressional force. (a) What pressure is created, assuming that the disk has a uniform circular cross section 2.00 cm in radius?

Calculate the pressure due to the ocean at the bottom of the Marianas Trench near the Philippines, given its depth is 11.0 km and assuming the density of sea water is constant all the way down. (b) Calculate the percent decrease in volume of sea water due to such a pressure, assuming its bulk modulus is the same as water and is constant.

(b) Is the answer reasonable? That is, does it seem to be consistent with what you have observed when using pencils?

The lintel of prestressed reinforced concrete in Figure P12.27 is 1.50 m long. The concrete encloses one steel reinforcing rod with cross-sectional area 1.50 cm2. The rod joins two strong end plates. The cross-sectional area of the concrete perpendicular to the rod is 50.0 cm2. Youngs modulus for the concrete is 30.0 109 N/m2. After the concrete cures and the original tension T1 in the rod is released, the concrete is to be under compressive stress 8.00 106 N/m2. (a) By what distance will the rod compress the concrete when the original tension in the rod is released? (b) What is the new tension T2 in the rod? (c) The rod will then be how much longer than its unstressed length? (d) When the concrete was poured, the rod should have been stretched by what extension distance from its unstressed length? (e) Find the required original tension T1 in the rod. Figure P12.27
