Which of the following is dimensionless?
The correct answer is Longitudinal strain.
Force: A force is an external agent that can change the state of rest or motion of an object, or deform it. Deforming force is a specific type of force that causes deformation. All types of strain are dimensionless because they are ratios of similar quantities. Stress and force, however, have definite dimensions derived from mass, length, and time.

What is the formula of velocity gradient?
What is the SI unit for measuring the luminous intensity?
