The Pisa Calculator is a useful tool for calculating the effects of the leaning angle of a tower, like the famous Leaning Tower of Pisa. It helps you determine how far the top of the tower is displaced horizontally from the base, the total height of the tower considering the lean, and the percentage of the lean relative to the tower’s height.

## Understanding the Calculator’s Purpose and Functionality

The Pisa Calculator is designed to perform three main calculations based on the height of a tower and its angle of lean. These calculations include:

**Horizontal Displacement**: This is the distance the top of the tower is displaced horizontally from the base due to the lean.Formula:Horizontal Displacement=Height×sin(Angle)\text{Horizontal Displacement} = \text{Height} \times \sin(\text{Angle})Horizontal Displacement=Height×sin(Angle)**Total Height**: This is the total vertical height of the tower from the top to the base.Formula:Total Height=Height×cos(Angle)\text{Total Height} = \text{Height} \times \cos(\text{Angle})Total Height=Height×cos(Angle)**Lean Percentage**: This represents the percentage of the lean compared to the height of the tower.Formula:Lean Percentage=(Horizontal DisplacementTotal Height)×100\text{Lean Percentage} = \left(\frac{\text{Horizontal Displacement}}{\text{Total Height}}\right) \times 100Lean Percentage=(Total HeightHorizontal Displacement)×100

## Step-by-Step Examples

Let’s go through an example to understand how the Pisa Calculator works.

**Example**:

- Height of the Leaning Tower: 56 meters
- Angle of Lean: 5 degrees

**Calculate Horizontal Displacement**:Horizontal Displacement=56×sin(5∘)≈56×0.0872≈4.88 meters\text{Horizontal Displacement} = 56 \times \sin(5^\circ) \approx 56 \times 0.0872 \approx 4.88 \text{ meters}Horizontal Displacement=56×sin(5∘)≈56×0.0872≈4.88 meters**Calculate Total Height**:Total Height=56×cos(5∘)≈56×0.9962≈55.79 meters\text{Total Height} = 56 \times \cos(5^\circ) \approx 56 \times 0.9962 \approx 55.79 \text{ meters}Total Height=56×cos(5∘)≈56×0.9962≈55.79 meters**Calculate Lean Percentage**:Lean Percentage=(4.8855.79)×100≈8.75%\text{Lean Percentage} = \left(\frac{4.88}{55.79}\right) \times 100 \approx 8.75\%Lean Percentage=(55.794.88)×100≈8.75%
