What is the efficiency of a machine, given mechanical advantage is 2 and velcoity ratio is 4?
Step 1: Given data:
Mechanicaladvantage,M.A=2Velocityratio,V.R=4
Step 2: Finding the efficiency of the machine:
Efficiency=M.AV.R=24=0.5
Thus, the efficiency of a machine with mechanical advantage 2 and velocity ratio 4 is 0.5
Derive a relationship between mechanical advantage, velocity ratio and efficiency of a machine.
(a) State the relationship between mechanical advantage, velocity ratio and efficiency.
(b) Name the term that will not change for a machine of a given design.
Prove that the efficiency of a machine is the ratio between mechanical advantage and the velocity ratio?
