Question

Young 's modulus of steel is 2.0 xx 10^(11)N m//(2) . Express it is "dyne"/cm^(2).

Answer 1

Explanation:

Young's modulus = 2× 10^11 N/ m^2

1N= 10^5 dyne

1m^2 = 10^4 cm^2

so Young's modulus = 2× 10^11 × 10^5 × 10^-4

= 2× 10^12 dyne/cm^2

Answer 2

Young 's modulus = 2.0 x $10^1^2$  dyne/cm²

Given:

Young 's modulus of steel is 2.0 x $10^1^1$ N/ m²

To find:

Young 's modulus in  dyne/cm²

Concept used:

1 N = $10^5$ dyne

1 meter² = $10^4$ cm²

Explanation:

Young 's modulus:

With in the elastic limit stress is directly proportional to strain the proportionality constant is called as Young 's modulus.

That is Young 's modulus = $\frac{Stress}{Strain}$

Young 's modulus = 2.0 x $10^1^1$ N/ m²

                              =  2.0 x $10^1^1$ × $\frac{10^5}{10^4}$

                              = 2.0 x $10^1^2$

Young 's modulus = 2.0 x $10^1^2$  dyne/cm²
