A man lifts various loads with the same lever. The distance of the applied force from the fulcrum is 1.00 m, and the distance from the fulcrum to the load is 0.250 m. What is the mechanical advantage of the lever?
What is the ideal mechanical advantage of the lever? What is the efficiency of the lever? show work.
Ma=4
To find the mechanical advantage of the lever, we can use the formula:
Mechanical Advantage = Load Distance / Effort Distance
In this case, the Load Distance is 0.250 m and the Effort Distance is 1.00 m.
Mechanical Advantage = 0.250 m / 1.00 m = 0.25
So, the mechanical advantage of the lever is 0.25.
The ideal mechanical advantage is calculated using the formula:
Ideal Mechanical Advantage = Effort Distance / Load Distance
In this case, the Effort Distance is 1.00 m and the Load Distance is 0.250 m.
Ideal Mechanical Advantage = 1.00 m / 0.250 m = 4
So, the ideal mechanical advantage of the lever is 4.
To find the efficiency of the lever, we can use the formula:
Efficiency = Mechanical Advantage / Ideal Mechanical Advantage
Given that the mechanical advantage is 0.25 and the ideal mechanical advantage is 4:
Efficiency = 0.25 / 4 = 0.0625
So, the efficiency of the lever is 0.0625 or 6.25%.
