17.3.5. Structural Analysis (Stress-Strain via PDEs)

Try these first

1. 1.

   Define stress and strain.

   Hint

   Think of stress as pressure and strain as stretching.

2. 2.

   What does Hooke's Law state?

   Hint

   Remember the relationship between force and deformation.

3. 3.

   Which law states that stress is proportional to strain?

   • Newton's Law
   • Hooke's Law
   • Bernoulli's Principle

   Hint

   Think about materials that return to their original shape after deformation.

4. 4.

   True or False: Strain measures how much a material stretches or compresses.

   • True
   • False

   Hint

   Focus on the definition of strain.

5. 5.

   A beam supports a load of 500N. If the cross-sectional area is 0.02m², calculate the stress experienced by the beam.

   Hint

   Use the stress formula.

6. 6.

   A material has a Young’s Modulus of 200 GPa and experiences a stress of 100 MPa. Calculate the expected strain.

   Hint

   Remember the relationship defined by Young's Modulus.
