Find required diameter if elongation not to exceed 0.005″ and find required diameter if unit stress not exceed 24,000 psi.

ksi of steel = 20,000,000 psi modulus of elasticitY = hooke’s law or young’s modulus (same thing)

f= P/A

Unit stress (f) is equal to the load (P) divided by the cross sectional area (A).

Divide into rectangles and calculate the area of each rectangle.
