Concept explainers

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Question

### Problem Description

Consider the shaded area shown in Figure 1. Suppose that:
- \( a = 130 \, \text{mm} \)
- \( b = 150 \, \text{mm} \)
- \( r = 80 \, \text{mm} \)

### Task

**Part A**
Determine the moment of inertia of the shaded area about the \( x \) axis.

**Instructions:**
Express your answer to three significant figures and include the appropriate units.

### Input Box
- \( I_x = \) [Input Value] [Units]

### Illustration Description

#### Figure

- The figure is a geometric shape composed of a trapezoid with a circular cutout.
- The trapezoid is positioned in the Cartesian coordinate system with the base along the \( x \) axis.
- The distance along the \( y \) axis from the origin to the base of the trapezoid is \( b \).
- The top horizontal side of the trapezoid is \( a \).
- The bottom horizontal side of the trapezoid extends to \( a + b + a = 2a + b \).
- The vertical height of the trapezoid along the \( y \) axis is \( b \).
- A circular cutout with radius \( r \) is positioned towards the left side along the \( y \) axis.
