Question

Which of the following quantities has the same unit as pressure?

• A. Strain
• B. Stress
• C. Momentum
• D. Torque

Answer 1

The correct option is B Stress

Unit of stress $=\left(\frac{\text{Force}}{\text{Area}}\right)\to {\text{Nm}}^{-2}$
[SI unit]
Unit of Pressure $=\left(\frac{\text{Force}}{\text{Area}}\right)\to {\text{Nm}}^{-2}$ [SI unit]
Unit of Momentum $=\left(m.v\right)\to {\text{kg m s}}^{-1}$ [SI unit]
Unit of Torque $(F.r_{\perp })\to \text{N-m}$
Unit of Strain $\left(\frac{\Delta l}{l}\right)\to$ no units
