Answer:
2.5 * 10^12 Nm-2
Explanation:
Stretching force = 20 * 10^3 N
diameter = 10 * 10^-3 m
extension = 0.2 * 10^-3 m
length of bar = 2m
Young Modulus = stress/strain
stress = Force/Area
Strain = extension/length
Young Modulus = Force/Area/extension/length
But area = πr^2 = 3.142 * (5 *10^-3)^2 = 7.9 * 10^-5 m^2
Stress = 20 * 10^3/7.9 * 10^-5 = 2.5 * 10^8 Nm-2
Strain = 0.2 * 10^-3/2 = 1 * 10^-4
Young Modulus = 2.5 * 10^8/1 * 10^-4
Young Modulus = 2.5 * 10^12 Nm-2
In the United States, the U.S. dollar determines the value of money. There are three ways to measure the value of the dollar. The first is how much the dollar will buy in foreign currencies.
