A 1.25 in. by 3 in. rectangular steel bar is used as a diagonal tension member in a bridge truss. The diagonal member is 20 ft long, and its modulus of elasticity is 30,000,000 psi. If the strain in the diagonal member is measured as 0.001200 in./in., determine:
The axial stress (precision of 1,000)
The tension force in the bar (precision of 10,000)
The elongation of the member (precision of 0.00)
