Question

The 45° strain rosette shown below is mounted on the surface of a thin shell. The following readings are obtained for each gauge: \( \varepsilon_a = -200 \times 10^{-6} \), \( \varepsilon_b = 300 \times 10^{-6} \), and \( \varepsilon_c = 250 \times 10^{-6} \). Determine the principal strains.

**Diagram Explanation:**

- The diagram illustrates a 45° strain rosette composed of three strain gauges labeled \(a\), \(b\), and \(c\).
- Gauge \(a\) is positioned at a 45° angle to the left of the vertical line.
- Gauge \(b\) is aligned vertically.
- Gauge \(c\) is positioned at a 45° angle to the right of the vertical line.
- The angles between each adjacent gauge, as shown by the arcs, are 45° each.

The objective is to calculate the principal strains from the readings obtained from these gauges.
