1.2.1. Young’s Modulus (E)

Try these first

1. 1.

   Define Young's Modulus.

   Hint

   Think about the relationship between stress and strain.

2. 2.

   What is the formula for strain?

   Hint

   Reference the measurements taken during an experiment.

3. 3.

   What is Young's Modulus?

   • A measure of thermal conductivity
   • The ratio of stress to strain
   • The weight of a material

   Hint

   Think about what Young's Modulus measures.

4. 4.

   True or False: Young's Modulus can vary with the temperature of the material.

   • True
   • False

   Hint

   Consider factors that influence material properties.

5. 5.

   A material rod elongates 6 mm under a load of 1500 N. If the original length was 1.5 m and the cross-sectional area is 5 cm², calculate the Young's Modulus.

   Hint

   Ensure units are consistent when calculating stress and strain.

6. 6.

   Discuss how Young’s Modulus could influence the choice of materials in building a skyscraper.

   Hint

   Think about the vertical and horizontal forces acting on tall buildings.
