## Solution to Problem 226 Biaxial Deformation

**Problem 226**

A 2-in.-diameter steel tube with a wall thickness of 0.05 inch just fits in a rigid hole. Find the tangential stress if an axial compressive load of 3140 lb is applied. Assume ν = 0.30 and neglect the possibility of buckling.

## Solution to Problem 225 Biaxial Deformation

**Problem 225**

A welded steel cylindrical drum made of a 10-mm plate has an internal diameter of 1.20 m. Compute the change in diameter that would be caused by an internal pressure of 1.5 MPa. Assume that Poisson's ratio is 0.30 and E = 200 GPa.

## Shearing Deformation

**Shearing Deformation**

Shearing forces cause shearing deformation. An element subject to shear does not change in length but undergoes a change in shape.

The change in angle at the corner of an original rectangular element is called the shear strain and is expressed as

The ratio of the shear stress τ and the shear strain γ is called the *modulus of elasticity in shear* or modulus of rigidity and is denoted as G, in MPa.

The relationship between the shearing deformation and the applied shearing force is

where V is the shearing force acting over an area A_{s}.
