## Calculation Example – Torsional moment-Stress.

Calculate the max stress because of torsional moment on the outer layer of a steel hollow rod when two forces act on it from a distance of 200mm from the center.

## Calculation Example – Reinforced Concrete Column at Stress.

A rectangular column (400mmX400mm) is constructed of concrete and four steel reinforcing rebars. An axial force of 1000KN is subjected on the column. What is the diameter of the steel bars if the ¼ of the load is transferred to the steel bars and ¾ is transferred to the concrete? ( EST=200GPa, Ec=25GPa)

## Calculation Example – Calculate shear stress for temperature load.

A copper bar with a rectangular cross section is held without stress between rigid supports. The temperature of the bar is raised 50°C. Determine the maximum shear stress t. (Assume α= 17.5 x 10-6/°C and E =120 GPa.)

## Calculation Example - Annular cross section, Stress.

A strain gage is located at D on the surface of the rod AB. The average normal stress on the rod is σ when the rod is subjected to forces F as on the sketch. Assume that the cross section at D is annular and the outer diameter DEXT, calculate the inner diameter DINT of the cross section at D.

## Calculation Example – Plane stress.

Calculate the stresses acting on an element oriented at an angle θ= 60° from the x axis, where the angle θ is positive when counterclockwise.
