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:

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%

¿En dónde compras larimar?

disa [49]

Larimar es la piedra nativa de la República Dominicana. Es una pectolita y se encuentra solo en la República Dominicana. Se está realizando alguna copia de larimar, pero la mayor parte de lo que se vende es auténtica. El larimar más común es un azul claro con marmoleado blanco en todas partes.

¡Espero que esto te ayude y tengas un gran día! :)
