4. A bar of solid circular cross section is loaded in tension by forces P (see figure). The bar has length L =16.0 in. and diameter d = 0.50 in. The material is a magnesium alloy having modulus of elasticity E = 6.4 x10° psi. The allowable stress in tension is oallow = 17,000 psi, and the elongation of the bar must not exceed 0.04 in. What is the allowable value of the forces L. P?
