Question

which of the following has no dimensions? a) hydraulic stress b) Poisson ratio c) young's modulus d) bulk modulus ​

Answer 1

c) Young's modulus is correct answer

The Young's modulus (E) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress (σ) to tensile strain (ε). Where stress is the amount of force applied per unit area (σ = F/A) and strain is extension per unit length (ε = dl/l).

Answer 2

Answer:

A) Hydraulic stress

Explanation:

• Hydraulic stress is the internal restoring force per unit area in this scenario, and its magnitude is equivalent to hydraulic pressure (applied force per unit area). There are no units or dimensional formulas in it.

• The dimensional formula for stress is   $7[ML^{-1} T^{-2} ].$  Hydraulic stress is a measure of internal force per unit area on liquids....

• Hydraulic stress is a measurement of the internal force acting on liquids per unit area. When the force is applied by the fluid on the body, hydraulic stress is the restoring force per unit area.
