The Ladder Height Calculator is designed to calculate the vertical height a ladder reaches when it is placed at an angle against a wall or another vertical surface. This is particularly useful for ensuring that the ladder is set up at a safe and effective angle, minimizing the risk of falling and maximizing reach.
Inputs:
- Ladder Angle (θ): This is the angle in degrees between the ground and the ladder. The angle helps determine how steeply the ladder is set.
- Distance from Base (d): This is the horizontal distance from the base of the ladder to the wall or surface it leans against.
Formula: The height of the ladder can be calculated using the formula: h=dcos(θ)h = \frac{d}{\cos(\theta)}h=cos(θ)d Where:
- hhh is the ladder height.
- ddd is the distance from the base.
- θ\thetaθ is the ladder angle in degrees converted to radians for calculation.
Step-by-Step Examples
Example 1:
- Ladder Angle (θ): 60 degrees
- Distance from Base (d): 5 feet
Calculation: h=5cos(60∘)h = \frac{5}{\cos(60^\circ)}h=cos(60∘)5 h≈50.5h \approx \frac{5}{0.5}h≈0.55 h=10 feeth = 10 \text{ feet}h=10 feet
Output: The height of the ladder is approximately 10 feet.
Example 2:
- Ladder Angle (θ): 45 degrees
- Distance from Base (d): 4 feet
Calculation: h=4cos(45∘)h = \frac{4}{\cos(45^\circ)}h=cos(45∘)4 h≈40.707h \approx \frac{4}{0.707}h≈0.7074 h≈5.66 feeth \approx 5.66 \text{ feet}h≈5.66 feet
Output: The height of the ladder is approximately 5.66 feet.
