The tensile load applied in axial direction on a rectangular plate is 100 N. If the area of rectangular plate is 4 mm2. The stress develop in the plate will be:
1. 2.5 MPa
2. 15 MPa
3. 25 MPa
4. 50 MPa

Correct Answer - Option 3 : 25 MPa

Concept:

$Stress\;(\sigma) = \frac{Load}{Area\; of\; cross\; section }$

Here, the Area of the cross-section is perpendicular to the applied load.

Calculation:

Given:

Load = 100 N, Area of rectangular plate = 4 mm2.

$Stress\;(\sigma) = \frac{Load}{Area\; of\; cross\; section }$

$\sigma = \frac{100}{4}$ = 25 N/mm2 or MPa

∴ The stress developed in the plate is 25 MPa
