A steel rod with a cross-sectional area of 0.25 in2 is stretched between two fixed points. The tensile force in the rod at 70 oF is 1,200 lb. Use α = 6.5 x 10-6/ oF and E = 29 x 106 psi. What will be the stress in ksi at 0 oF ? Use two decimal places.
Thanks

A rod with cross-sectional area of 1002 is stretched between two fixed points such that the initial tensile load is 10kN. The road has a modulus of elasticity equal to 180GPa and a coefficient of linear expansion of 0.00001m/m-°C. The initial tension is designated such that the rod will have a zero stress when there is a certain change in temperature of the rod environment. What is the temperature (in °C, 2 decimal places)?

Four steel rods each with a cross-sectional area of 1in 2 are embedded in a 5-in diameter light aggregate concrete cylinder. The steel has a yield strength of 36000 psi and a modulus of elasticity of 30x10n6 psi. Assume a very strong interface between the steel and the concrete causes them to experience identical deflections. A rigid plate is placed over both ends of the cylinder and a compressive axial force of 100,000 lb is applied. The stress (psi) induced...

326 СНАРТER 6 BENDING EXAMPLE 6.18 The reinforced concrete beam has the cross-sectional area shown in Fig. 6-39a. If it is subjected to a bending moment of M = 60 kip ft determine the normal stress in each of the steel reinforcing rods and the maximum normal stress in the concrete. Take Est = 29(10) ksi and Econc = 3.6(103) ksi SOLUTION Since the beam is made of concrete, in the following analysis we will neglect its strength in supporting...
