A bridge a mass of 800 kg and is able to support up to 4 560 kg. What is its structural efficiency?
Answer:4560÷800=5.4
Explanation:
Determine the dimensions for W if W = P L^3 / (M V^2) where P is a pressure, L is a length, M is a mass, and V is a velocity.
a. M
b. L / T
c. M L / T^2
d. M / (L T^2)
e. No dimensions
Correct answer is option E. No dimensions
As we know formula Pressure (P) is [tex]\frac{F}{A}[/tex]
also,
Dimensional formula of Pressure is [tex]M^{1}L^{-1}T^{-2}[/tex]Dimensional formula of length is L Dimensional formula of mass is MDimensional formula of velocity is [tex]L^{1} T^{-1}[/tex]So, as given W=[tex]\frac{P*L^{3} }{M*V^{2} }[/tex]
Dimensional formula of W =[tex]\frac{M^{1}L^{-1}T^{-2} L^{3} }{M^{1} L^{2}T^{-2} }[/tex]
since all terms get cancelled
Work is dimensionless i.e no dimensions
