Question

if force (F) , velocity (v) and acceleration (A) are taken as fundamental units instead of mass, length and time, express pressure and impulse in term of F,V and A.​

Answer 1

Answer:

v^−4Fa^2

Explanation:

Young's Modulus (Y)=Stress/Strain=F/A/l/L

F is a fundamental quantity. Dimension of length in new fundamental units,

L=v2a

Therefore, A has a dimension,

A=v^4/a^2

Strain is dimensionless.  

Dimension of Young's Modulus,

Y=F/v^4/a2=v^−4Fa^2
