Question

Young modulus of steel is 19 * 10^11 N/m^2. Express it in:

A) Pascals (Pa)
B) Megapascals (MPa)
C) Gigapascals (GPa)
D) Kilopascals (kPa)

Answer 1

To convert the Young modulus of steel, 19 * 10^11 N/m^2, into different units: it is already in Pascals; divide by 1 million to get Megapascals; divide by 1 billion to get Gigapascals; multiply by 1000 for Kilopascals.

Step-by-step explanation:

To convert the Young modulus of steel, 19 x 10^11 N/m^2, into different units:

A) To Pascals (Pa) - since 1 Pascal equals 1 N/m^2, the Young modulus is already in Pascals.

B) To Megapascals (MPa) - divide the Young modulus by 1 million (10^6) to get the value in Megapascals.

C) To Gigapascals (GPa) - divide the Young modulus by 1 billion (10^9) to get the value in Gigapascals.

D) To Kilopascals (kPa) - multiply the Young modulus by 1000 to get the value in Kilopascals.
