Detailed Procedure to find Young's Modulus of L1 = 55 mm, L2 = 54.5 mm, A = 319.16 mm² and F = 25 N

Young's Modulus states that a measure of elasticity is equal to the ration of the stress acting on a substance to the strain produced. Young's Modulus is also known as modulus of elasticity.

The formula to calculate Young's Modulus is:

E =
σ / ε

Where,

E = Young's modulus

σ = Stress

ε = Strain


Step by Step Solution to find Young's Modulus :

Given that,

Stress (σ) = ?

Strain (ε) = ?

Initial Length (L1) = 55 mm

Final Length (L2) = 54.5 mm

Change in Length (ΔL) = ?

Area (A) = 319.16 mm²

Force (F) = 25 N

Calculating Stress

Stress (σ) =
Force (F) / Area (A)

=> Convert the Area (A) 319.16 mm² to "square meter (m²)"

F = 319.16 ÷ 1000000

F = 0.000319 m²

Substitute the value into the formula

Stress (σ) =
25 / 0.00031916000000000003

Stress (σ) = 78330.617872 Pa

Calculating Strain :

Strain (S) =
Change in Length ( ΔL ) / Initial Length ( L2 )

=> convert the L1 value to "meters (m)" unit

r = 55 ÷ 1000

r = 0.055 m

=> convert the L1 value to "meters (m)" unit

r = 54.5 ÷ 1000

r = 0.0545 m

ΔL = 0.0545 - 0.055

ΔL = -0.0005 m

Substitute the value into the formula

Strain (S) =
-0.0005 / 0.055

Strain (S) = -0.009091

As we got all the values we can calculate Young's Modulus

E =
78330.617872 / -0.009091

E = -8616367.965911 Pa

∴ Youngs's Modulus (E) = -8616367.965911 Pa
