Question

An 8-kN force is applied over an area of 2 cm^2. What is the stress?

4 MPa


4 kPa


40 kPa


40 MPa


4 Pa

Answer 1

Option a (4 MPa) is the right answer.

Explanation:

The given values are:

Force,

F = 8 kN

Area,

A = 2 cm²

The stress will be:

⇒
`\sigma = (Force)/(Area)`

By substituting the given values, we get

`=(8)/(2)`

`= 4 \ MPa`
