Question 1

What is the primary purpose of a gradient?

  • To find maxima
  • To determine the direction of change
  • To calculate area

💡 Hint: Think about how the shape of a hill indicates steepness.

Question 2

True or False: The displacement vector in cylindrical coordinates can have three unique components.

  • True
  • False

💡 Hint: Recall the terms used in cylindrical representation.

Challenge Problems

Push your limits with challenges.

Question 1

If a hollow cylinder experiences a radial displacement of 5 cm and a hoop displacement of 3 cm, calculate the strains ε_rr and ε_θθ assuming initial lengths were 50 cm.

💡 Hint: Use the formula for strain: ε = ΔL / L₀.

Question 2

A cylindrical structure shows a non-uniform displacement due to varying internal pressure. Describe how this affects the overall strain calculations and what assumptions might need adjusting.

💡 Hint: Think about how pressure changes can result in different strain responses.
