Calculating Horizontal Distance from Measured Distance and Gradient
To calculate the horizontal distance from a measured distance and gradient, we need to use the formula:
Horizontal distance = Measured distance / (Square root of (gradient^2 +1))
Where,
- Measured distance is the distance measured along the slope
- Gradient is the ratio of the vertical change to the horizontal change (for example, 1:16 means for every 1 unit of vertical change, there is 16 units of horizontal change)
Applying the Formula to the Given Values
In this case, the measured distance is 18.5m and the gradient is 1:16.
So, first we need to convert the gradient ratio to a decimal:
1:16 = 1/16 = 0.0625
Then, we can substitute the values into the formula:
Horizontal distance = 18.5 / (Square root of (0.0625^2 +1))
= 18.5 / (Square root of 0.00390625 +1)
= 18.5 / (Square root of 1.00390625)
= 18.5 / 1.0019509
= 18.46m (rounded to two decimal places)
Therefore, the horizontal distance is 18.46m.
Conclusion
To calculate the horizontal distance from a measured distance and gradient, we need to use the formula: horizontal distance = measured distance / (Square root of (gradient^2 +1)). In this case, the horizontal distance is 18.46m when the measured distance is 18.5m and the gradient is 1:16.
