Question
![**Shear Strain Calculation in a Uniformly Deformed Rectangular Plate**
**Problem Statement:**
A thin rectangular plate is uniformly deformed, as shown in the diagram. Determine the shear strain \( \gamma_{xy} \) at point P. Assume:
- \( a = 20 \text{ in.} \)
- \( b = 27 \text{ in.} \)
- \( c = 0.13 \text{ in.} \)
- \( d = 0.14 \text{ in.} \)
**Diagram Description:**
The diagram illustrates a rectangular plate deformed into a parallelogram:
- The undistorted plate is represented by a light-colored rectangle with vertices labeled P, Q, R, and S.
- The deformed plate is shown as a darker parallelogram with dashed edges parallel to the original rectangle.
- The dimensions of the plate are as follows:
- \( a \) is the horizontal distance from P to Q, measured along the x-axis (20 inches).
- \( b \) is the vertical distance from P to R, measured along the y-axis (27 inches).
- \( c \) is the horizontal displacement at the top-right corner S from its original position (0.13 inches).
- \( d \) is the vertical displacement at point R from its original position (0.14 inches).
- Axes:
- The x-axis is horizontal.
- The y-axis is vertical.
**Calculated Solution:**
\[ \gamma_{xy} = 11.7 \; \mu\text{rad} \]
This problem demonstrates the calculation of shear strain for a uniformly deformed plate by using specified displacements to establish strain at a given point. The final result provides the shear strain at point P in micro-radians (\( \mu\text{rad} \)).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb0830934-b0ff-4672-88dc-560265a97e08%2F0424365e-9339-4179-b80f-73d01b5e63d6%2F1j7z8e_processed.png&w=3840&q=75)
