Show hintHide hint
Consider how clay behaves when shaped.
Question 5.
A sports car's suspension system uses springs that have a Young's Modulus of 300 MPa. If the suspension compresses by 0.01 m under a load, what is the stress applied to the suspension?
Show hintHide hint
Use the relationship of Young's Modulus with stress and strain.
Question 6.
Determine the total deformation of a metal rod subjected to a tensile force of 600 N and has a Young's Modulus of 150 GPa with a length of 2 m and a cross-sectional area of 0.005 m².
Show hintHide hint
Use stress and Young's modulus to find strain, then deformation.
