Given: The hanging pyramid shown below has a height L = 3 ft and a square cross- section with side length bo = 6 in at y = 0 ft that reduces linearly to 0 in at y = L The pyramid is made of steel with an elastic modulus of E 29000 ksi and unit weight of y 490 lb/ft3. Assume that the weight acts in the positive y-direction toward the point of the pyramid bo bo L y
