Young’s modulus of steel is 1.9 × 10^11 N/m2 . When expressed in CGS units of dynes/cm2, it will be equal to
1.9 * 10^12
Y = 1.9×10^11 N/m2
as 1N = 105 dyne , 1m^2 = 104 cm^2
Y = 1.9×10^11 × 10^5 / 10^4
= 1.9×10^12 dyne / cm2
1.9 * 10^12
Y = 1.9×10^11 N/m2
as 1N = 105 dyne , 1m^2 = 104 cm^2
Y = 1.9×10^11 × 10^5 / 10^4
= 1.9×10^12 dyne / cm2
