Chapter 1, Problem 1.41QP
Estimate the tensile strength required to prevent cracking in a concrete-like material that is cast into a bar, 50 in. long, and is fully restrained at each end against axial movement. The concrete is initially cast and cured at a temperature of 100°F and subsequently cools to a temperature of 0°F. Assume that the modulus of elasticity is 5 million psi and the thermal coefficient is 5 × 10–6 in./in./°F.
