isosceles trapezoidal cross

A cantilever beam AB of isosceles trapezoidal cross section has length L= 0.8 m, dimensions b1=  80 mm, b2= 90 mm, and height h =110 mm (see figure). The beam is made of brass weighing 85 kN/m3 .

(a) Determine the maximum tensile stress σt and maximum compressive stress σc due to the beam’s own weight.

(b) If the width b1 is doubled, what happens to the stresses?

(c) If the height h is doubled, what happens to the stresses?
