What is the dimensional formula of stress and strain?
Stress is defined as the force per unit area.
Or, Stress = Force /Area = (m.a) ÷ (Area) = (M×cms/sec^2) /cms^2= (M× L/T^2) ÷ L^2= (M×L×T^-2)×L^-2 =M×L^-1×T^-2 .
Elastic stress is force normal to area/ the area..
What are dimensional constants?
[də′men·chən·əl ′kän·stənt] (physics) A physical quantity whose numerical value depends on the units chosen for fundamental quantities but not on the system being considered.

What is the dimensional formula of Young’s modulus?
The dimensional formula of Young’s modulus is [ML-1T-2].
What is the formula for tension?
Tension Formula. The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration. T = mg + ma.
What is the dimensional formula of surface tension?
Or, T = [M1 L1 T-2] × [L-1] = M1 T-2. Therefore, surface tension is dimensionally represented as M1 T-2.
What are dimensional formulas?
Dimensional formula (equation) (Definition) : An equation, which gives the relation between fundamental units and derived units in terms of dimensions is called dimensional formula (equation). In mechanics the length, mass and time are taken as three base dimensions and are represented by letters L, M, T respectively.
What is tension unit?
In physics, tension, as a transmitted force, as an action-reaction pair of forces, or as a restoring force, may be a force and has the units of force measured in newtons (or sometimes pounds-force).
What are the 7 fundamental dimensions?
In total, there are seven primary dimensions. Primary (sometimes called basic) dimensions are defined as independent or fundamental dimensions, from which other dimensions can be obtained. The primary dimensions are: mass, length, time, temperature, electric current, amount of light, and amount of matter.
What does dimensional mean?
The definition of dimensional is something a shape that can be measured. An example of dimensional is a physical object with length, width and depth, like a table. adjective.
