A load of 600N is lifted using a first class lever applying an effort of 350N .If the distance between the load and the effort i

Answer:

Efficiency = 85.5%

Explanation:

Given the following data;

Load = 600N

Effort = 350N

To find the efficiency of the lever, we would first of all determine the mechanical advantage and velocity ratio.

$Mechanical \; advantage = \frac {Load}{Effort}$

Substituting into the equation, we have;

$Mechanical \; advantage = \frac {600}{350}$

Mechanical advantage = 1.71

$Velocity \; ratio = \frac {Distance \; moved \; by \; effort}{Distance \; moved \; by \; load}$

Substituting into the equation, we have;

$Velocity \; ratio = \frac {60}{30}$

Velocity ratio = 2

Now, to find the efficiency of the lever

$Efficiency = \frac {Mechanical \; advantage}{Velocity \; ratio} * 100$

Substituting into the equation, we have;

$Efficiency = \frac {1.71}{2} * 100$

$Efficiency = 0.855 * 100$

Efficiency = 85.5%
