Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

### Educational Exercise: Analyzing Stress in a Bent Steel Strip

#### Problem Statement

A 920-mm (L) strip of steel with an elastic modulus \( E = 200 \) GPa is bent into a full circle by two applied couples. This is a multi-part question, and once submitted, you cannot return to this part of the question.

#### Diagram Explanation

- The circular bending of the steel strip is illustrated. The couples, denoted as \( M' \) and \( M \), are applied in opposite directions at the ends of the circular strip.
- A cross-section of the strip highlights its uniform thickness \( t \).
- The radius \( r \) of the circle formed by bending is implied from the full circular form.
- A detailed view of the cross-section shows an 8 mm width of the strip and a variable thickness \( t \).

#### Task

Determine the maximum allowable thickness \( t \) of the strip if the allowable stress in the steel is 420 MPa.

#### Calculation

- **Required Input:** Maximum thickness \( t \) of the steel strip.
- **Output Format:** "The maximum thickness \( t \) of the strip is _____ mm."

Complete the calculations and provide your answer for the thickness \( t \).
