A light elastic string of natural length I and modulus of elasticity is stretched by a

Question:

A light elastic string of natural length I and modulus of elasticity λ is stretched by a force T, causing the string to extend. In each of the following cases, work out the unknown value.

a. T = 15N, λ = 40N, I = 1.2m. Find the extension.

b. T = 25N, I = 1.5m, x = 0.5m. Find the modulus of elasticity.

c. T = (3λ - 11)N, I = 2 m, x = 0.5 m. Find the tension in the string.
