## Homework Statement

Cast iron has a strength in compression of about three to four times the strength in tension, depending upon the grade.

using the stress as a prime consideration, design the optimum T section for a cast iron beam using a uniform section thickness such that the compressive stress will be related to the tensile stress by a factor of 4

**2. Homework Equations**

TStress = (M*c1)/I

CStress = -(M*c2)/I

TStress = (M*c1)/I

CStress = -(M*c2)/I
