a load 500N is raised 0.2m by a machine in which an effort of 150N moves 1m. what is the work done on the load?

A force paralled to an inclined plane is used to raise a load of 500N through a height of 3M While the load moves a distance of 30M along the plane

(a) How much work is done on the load ? (b)if the efficency is 80% calculate the effort
(c)how much work is done by the effort

To find the work done on the load, we can use the formula:

Work = Force × Distance

Given:
Load = 500 N
Distance raised = 0.2 m
Effort = 150 N
Distance moved by effort = 1 m

Since the effort and load act in opposite directions, we need to calculate the net force. The net force can be found by subtracting the effort from the load:

Net Force = Load - Effort
Net Force = 500 N - 150 N
Net Force = 350 N

Now, we can calculate the work done on the load using the net force and distance raised:

Work = Net Force × Distance
Work = 350 N × 0.2 m
Work = 70 Joules

Therefore, the work done on the load is 70 Joules.

To find the work done on the load, we can use the formula:

Work = Force × Distance

In this case, the force is the effort applied by the machine, and the distance is the height at which the load is raised.

Given:
Force exerted by the machine (effort) = 150N
Distance moved by the effort = 1m
Height at which the load is raised = 0.2m

We need to calculate the work done on the load.

To solve this, we need to find the force required to lift the load. We can use the principle of mechanical advantage since the machine is providing an effort to move the load.

The mechanical advantage (MA) can be calculated using the formula:

MA = Load / Effort
MA = 500N / 150N
MA = 3.33

The mechanical advantage represents how much the machine multiplies the effort force to overcome the load.

Now, we can use the mechanical advantage to find the force required to lift the load:

Effort = Force / MA
Effort = 150N / 3.33
Effort = 44.94N (approximately)

Now that we know the force required to lift the load is approximately 44.94N, we can calculate the work done on the load using the formula:

Work = Force × Distance
Work = 44.94N × 0.2m
Work = 8.988 Nm (or Joules)

Therefore, the work done on the load is approximately 8.988 Nm (Joules).
