Distance of effort = 0.99m
Explanations:Note: IMA means Ideal Mechanical Advantage
When the Mechanical Advantage of a machine is ideal:
The effiiciency is 100%
The Mechanical Advantage equals the Velocity Ratio. That is, MA = VR
From the question:
IMA = 2.2
Since IMA = VR
VR = 2.2
Also note that the distance of the resistance is the distance moved by the load.
Distance of resistance = Distance of load = 0.45 m
[tex]\begin{gathered} VR\text{ = }\frac{Dis\tan ce\text{ moved by effort}}{\text{Distance moved by load}} \\ 2.2\text{ = }\frac{\text{Distance of effort}}{0.45} \\ \text{Distance of effort = 2.2}\times0.45 \\ \text{Distance of effort = }0.99\text{ m} \end{gathered}[/tex]
