Question

Calculate hypotenuse allowance for 30 metres, change when sloping ground is 20 Celsius

Answer 1

Answer:

Step-by-step explanation:

We know for 30 m length, h = 1.5

And given gradient is 1 in 20 i.e 1/20

So, the equation of slope correction is,

= h^2 / 2l

= 1.5^2 / 2*30 m

= 2.25 / 60m

= 0.0375 m or 3.75 cm
