Challenge Problems
Push your limits with advanced challenges
Consider a beam fixed at one end. If a force pulls on the free end creating a longitudinal strain of 0.01, calculate the new length if the original was 2 m.
💡 Hint: Use the formula for longitudinal strain.
A rectangular sheet experiences a shear strain that reduces the right angle between its sides to 85 degrees. Calculate the angle change.
