Question

A flexural member is fabricated from two flange plates 7-1/2 x ½ and a web plate 17 x 3/8. The yield stress of steel is 50 ksi. a. Compute the plastic modulus Z and the plastic moment Mp with respect to the major axis. b. Compute the elastic section modulus S and the yield moment My with respect to the major axis

Answer 1

Answer:

(a)

Plastic section modulus Z =92.72 in^3

Plastic moment Mp = 4636 kip-in

(b)

Elastic section modulus S = 80.88 in^3

Yield moment My = 4044 kip-in
