Introduction

In physics, an inclined plane is a flat surface that is tilted at an angle. It is a simple machine that helps to reduce the effort required to lift or move an object. The mechanical advantage of an inclined plane is a measure of how much it can reduce the effort required to lift an object. In this article, we will discuss the mechanical advantage of an inclined plane and how to calculate it.

What is Mechanical Advantage?

Mechanical advantage is a measure of the ratio of the output force to the input force. It is a way to describe how much a machine can amplify or reduce the force required to perform a task. In the case of an inclined plane, the mechanical advantage is a measure of how much it can reduce the effort required to lift an object.

Calculating Mechanical Advantage of an Inclined Plane

The mechanical advantage of an inclined plane can be calculated using the following formula:

Mechanical Advantage = Length of the inclined plane / Height of the inclined plane

Where:

Length of the inclined plane is the distance from the bottom of the inclined plane to the top.
Height of the inclined plane is the vertical distance from the bottom of the inclined plane to the top.

Example Problem

Let's consider an example problem to illustrate how to calculate the mechanical advantage of an inclined plane. Suppose we have an inclined plane with a length of 9 feet and a height of 3 feet. We want to calculate the mechanical advantage of this inclined plane.

Step 1: Identify the Length and Height of the Inclined Plane

The length of the inclined plane is 9 feet, and the height of the inclined plane is 3 feet.

Step 2: Plug in the Values into the Formula

Mechanical Advantage = Length of the inclined plane / Height of the inclined plane = 9 feet / 3 feet = 3

Step 3: Interpret the Result

The mechanical advantage of the inclined plane is 3. This means that the inclined plane can reduce the effort required to lift an object by a factor of 3.

Conclusion

In conclusion, the mechanical advantage of an inclined plane is a measure of how much it can reduce the effort required to lift an object. It can be calculated using the formula: Mechanical Advantage = Length of the inclined plane / Height of the inclined plane. By understanding the mechanical advantage of an inclined plane, we can design more efficient machines and systems that can reduce the effort required to perform tasks.

Answer

The correct answer is C. 3.
