Can you please explain @ Harish, Why you multiplied 10^4 with 24?

Tell me the right formula.
Suhasish Munshi said:

The correct steps:
(W^2 * L)÷(24 *P^2).
W=weight of tape in kg/m,
L=length of tape in m,
P= pull applied or tension in kg,
So, W= 5kg/50m= 0.1kg/m.
L=50m and P=5kg.
(W^2 * L)÷(24 *P^2).
W=weight of tape in kg/m,
L=length of tape in m,
P= pull applied or tension in kg,
So, W= 5kg/50m= 0.1kg/m.
L=50m and P=5kg.

Why you multiplying with P^2 in W? Please explain the formula.

Given:
(W)^2=(4kg )^2 = 16kg.
L=50.
p=5^2=25.
Sag correction = 16*50/24*25.
800/600 = -1.33ft.
Note: Sag correction is Always negative.
(W)^2=(4kg )^2 = 16kg.
L=50.
p=5^2=25.
Sag correction = 16*50/24*25.
800/600 = -1.33ft.
Note: Sag correction is Always negative.

((4/50)^2 * 50)/(24*5^2) = 0.0833m.
Y (4/50)----->w is the weight per meter length.
Y (4/50)----->w is the weight per meter length.

(5-4)^2*50/(24*5^2) = .0833.

Correction for sag = W^2*L / 24*P^2 , where w is in kg,N,kN etc.
Correction for sag = w^2*L^3 / 24*P^2 , where w is in kg/m, N/m etc.
Correction for sag = w^2*L^3 / 24*P^2 , where w is in kg/m, N/m etc.

.083 m is not the correct answer for given data.
Here, Given data will be same except W= 1kg
So, ( 1kg)^2 * (50 m) /[ 24 * ( 5kg)^2]= .083 m.
Here, Given data will be same except W= 1kg
So, ( 1kg)^2 * (50 m) /[ 24 * ( 5kg)^2]= .083 m.

You are correct, Thanks @Johny.
