Correct Answer - Option 4 : 10 N/m
2
The correct answer is option 1) i.e. 10 N/m2.
CONCEPT:
-
Shear stress (σ): It is the amount of resistive force per unit area of a body generated due to an externally applied force.
- Its SI unit is N/m2 and is represented by "σ".
- It is given by the formula:
\(\Rightarrow σ = \frac{F}{A}\)
Where F = Force applied in Newton and A = area of the body in m2
CALCULATION:
Given: Force on the body (F) = 10N and Area of the body (A) = 10000cm2 = 1m2
- Hence, the value of shear stress will be
\(\Rightarrow σ = \frac{F}{A}=\frac{10}{1}=10 \, Nm^{-2}\)
- Shear stress (σ) = 10N/m2.
