Question

A truck is pulling a car out of a ditch by means of a steel cable that is 9.1 m long and has a radius of 5 mm. When the car just begins to move,

Answer 1

According to the problem,
Length of steel cable l = 9.1 m
Radius r = 5 mm = 5 x 10~3 m
Tension in the cable F = 800 N
Young’s modulus for steel Y= 2 x 1011 N/m2
Change in length ∆l = ?

Answer 2

Answer:

Explanation:

According to the problem,

Length of steel cable l = 9.1 m

Radius r = 5 mm = 5 x 10~3 m

Tension in the cable F = 800 N

Young’s modulus for steel Y= 2 x 1011 N/m2

Change in length ∆l
