The pier is made of material having a specific weight g.
Chapter 1, Problem 1-57(choose chapter or problem)
The pier is made of material having a specific weight g. If it has a square cross section, determine its width w as a function of z so that the average normal stress in the pier remains constant. The pier supports a constant load P at its top where its width is \(w_{1}\).

ANSWER:
Problem 1-57The pier is made of material having a specific weight g. If it has a square cross section,determine its width w as a function of z so that the average normal stress in the pierremains constant. The pier supports a constant load P at its top where its width is w . 1 Step-by-step solution Step 1 of 2 ^Write the expression for stress assuming constant stress acting at top of the pier. P 1= A 1 P = 2 w1Here, P is the constant load acting on the pier, A i1 the constant-sectional area of the pier, andw 1s the width of the pier at its top.
