An infinitesimal square element PQRS is shown in the figure. The x and y axes are also marked in the figure. The strains on the element are given by 𝜀𝑥𝑥= 500 × 10−6, 𝜀𝑦𝑦= 100 × 10−6 and 𝜀𝑥𝑦= 0. Which of the following statements is/are CORRECT?
- A. Percentage change in length of the diagonal PR is 0.03.
- B. Change in angle between PR and QS is 4 × 10−4 rad.
- C. Change in angle between PR and QS is 2 × 10−4 rad.
- D. Percentage change in length of the diagonal QS is 0.03.
Answer: A. Percentage change in length of the diagonal PR is 0.03.; B. Change in angle between PR and QS is 4 × 10−4 rad.; D. Percentage change in length of the diagonal QS is 0.03.
