Explanation:
<u>Given the following data;</u>
Load = 600N
Effort = 350N
To find the efficiency of the lever, we would first of all determine the mechanical advantage and velocity ratio.
Substituting into the equation, we have;
Mechanical advantage = 1.71
Substituting into the equation, we have;

Velocity ratio = 2
Now, to find the efficiency of the lever
Substituting into the equation, we have;
<em>Efficiency = 85.5%</em>
The correct answer would be A
