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
slava [35]

Answer:

Efficiency = 85.5%

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.

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

<em>Efficiency = 85.5%</em>
