1.A w24x192 of a242 steel is to be used as a beam. what are the values of yield stress Fy ultimate tensile stees Fu and modulus of elasticity E for this beam?
2.For a thin spherical shell subjected to internal pressure, the ratio of volumetric strain to diametral strain is:
a>1.25
b>1.5
c>2.0
d>3.0
Please explain the ansewer properly
