How to Calculate Reading on Mechanical Bathroom Scale on Inclined Plane

What factors are considered when calculating the reading on a mechanical bathroom scale placed on an inclined plane?

- Person's mass: 101.5 kg

- Inclination angle: 18.9 degrees

- Reading unit: kg

Factors to Consider

When calculating the reading on a mechanical bathroom scale placed on an inclined plane, several factors need to be taken into account:

1. Person's Mass: The mass of the person stepping on the scale plays a significant role in determining the reading.

2. Inclination Angle: The angle of the inclined plane with respect to the horizontal affects the normal force and the reading on the scale.

3. Reading Unit: The desired unit of measurement for the reading, whether it is in kilograms, pounds, or newtons, will also impact the calculation.

Calculating the reading on a mechanical bathroom scale on an inclined plane involves considering the person's weight, the angle of the plane, and the conversion factor for the desired unit. In the given scenario, the person has a mass of 101.5 kg and steps on a scale placed at an angle of 18.9 degrees with the horizontal.

To calculate the reading on the scale, we first determine the weight of the person by multiplying the mass by the acceleration due to gravity. However, since the scale is on an inclined plane, we need to find the weight component perpendicular to the plane to calculate the normal force acting on the person. This normal force will give us the reading on the scale.

Using trigonometric functions and conversion factors, we can accurately calculate the reading in the desired unit, whether it is in kilograms or newtons. Understanding these factors and their role in the calculation is essential for accurately determining the reading on a mechanical bathroom scale in various scenarios.
