Question

A uniform edge load of w1 = 530 lb/in. and w2 = 320 lb/in. is applied to the polystyrene specimen. Ep = 597(103)psi and νp = 0.25.

1) Part A: If the specimen is originally square and has dimensions of a = 1 in ., b = 2 in., and a thickness of t = 0.35 in. , determine its new dimension a′ after the load is applied.

2) Part B: Determine its new dimension b′ after the load is applied.

3) Part C: Determine its new dimension t′ after the load is applied. 

The image shows a graphical representation of a rectangular object subjected to uniform pressures on its surfaces. The diagram consists of a rectangle with arrows indicating forces applied to the top, bottom, and sides.

**Dimensions and Forces Explained:**

- The rectangle has a height labeled as \( a \) and a width labeled as \( b \).
- The top and bottom of the rectangle are subjected to horizontal forces, indicated by arrows pointing inward toward the rectangle. These forces are labeled as \( w_2 \).
- The sides of the rectangle experience vertical forces, shown by arrows pointing inward toward the rectangle. These forces are labeled as \( w_1 \).

This setup may represent a section of a material or system under compressive forces, often used to analyze stress and strain in engineering and physics contexts. The uniform distribution of arrows implies consistent application of pressure across the surfaces.
