Two persons pull a rope towards themselves. Each person exerts a force of 100 N on the rope. Find the Young modulus of the material of the rope if it extends in length by 1 cm. Original length of the rope = 2 m and the area of cross section = 2 cm2.
1 × 108 N m-2
Given, Force,
Cross-sectional area of rope,
Length of rope,
Extension is rope,
We know, stress,
And strain is given by ,
Young’s modulus then becomes,
