A) If the modulus of elasticity of the material is E = 1870 MPa , what is Poisson's ratio?

B)The block is subjected to a force V that produces a deflection of Δ = 0.15 cm . What is the applied force?

The image shows a geometric figure consisting of a rectangle with additional dashed lines forming a quadrilateral on the right side. 

In the shaded blue area:

1. There is an angle labeled γ (gamma) in the top left corner of the rectangle.
2. Another angle labeled \( \frac{\pi}{2} - \gamma \) is adjacent to the angle γ.

The dashed lines extending from the rectangle do not have additional labels or angles, suggesting that the focus is on the angles within the rectangle. The rectangle depicts a situation where two angles sum to \( \frac{\pi}{2} \), illustrating a complementary angle relationship.

### Educational Content: Understanding Shear Stress-Strain in Materials

**Text:**

A metal block is part of an industrial motor mount, has dimensions \( d_1 = 3 \, \text{cm} \), \( d_2 = 3.7 \, \text{cm} \), and \( d_3 = 4 \, \text{cm} \), and is made of a material with the shear stress-strain curve shown. Use this block to answer the following questions. Note: the given curve has a shape similar to that for a typical metal, but the curve has been drawn using straight lines, and the yield point has been moved to a higher strain than is typical, to make the graph easier to read.

**Diagram Explanation:**

1. **Diagram of Metal Block:**

   The diagram shows a three-dimensional representation of a metal block with the labeled dimensions:
   - \( d_1 = 3 \, \text{cm} \)
   - \( d_2 = 3.7 \, \text{cm} \)
   - \( d_3 = 4 \, \text{cm} \)

   The diagram also illustrates the concepts of shear deformation, with indicated shear strain (\( \gamma \)) and shear displacement (\( \Delta \)).

2. **Shear Stress-Strain Graph:**

   - **Vertical Axis (Y-axis):** Represents shear stress (\( \tau \)) measured in megapascals (MPa), ranging from 0 to 60 MPa.
   - **Horizontal Axis (X-axis):** Represents shear strain (\( \gamma \)) ranging from 0 to 0.40.
   - The graph depicts a linear increase in shear stress with strain up to a point, indicative of elastic behavior, followed by a decrease, suggesting the yield point and potential plastic deformation.
  
This educational content helps learners understand and interpret the shear stress-strain behavior of materials, a key aspect in engineering and materials science.
