Answer:
3.12 x 10^-5 m
Explanation:
Length of steel column, L = 4 m
diameter, d = 0.2 m
radius = half of diameter = 0.1 m
Young's modulus, Y = 2 x 10^11 N/m^2
Mass of truck, m = 5000 kg
Force, F = mass of truck x acceleration due to gravity
F = 5000 x 9.8 = 49000 N
Area of crossection of cable,
A =
Let ΔL be the shrink in length of cable, then by the formula of Young's modulus
ΔL = 3.12 x 10^-5 m
Thus, the shrink in the length of cable is 3.12 x 10^-5 m.
