Question

If a system pulley has a velocity ratio of 6 and mechanical advantage of 5 the system is used to raise a load of 3000N through 10m calculate work done by effort

Answer 1

To calculate the work done by the effort, we need to use the formula:

work = force x distance

We know the force raised (load) is 3000N and the distance it is raised is 10m. But we need to calculate the force applied by the effort.

The mechanical advantage (MA) is the ratio of the load to the effort:

MA = load / effort

5 = 3000 / effort

effort = 3000 / 5

effort = 600N

Now, we can calculate the work done by the effort:

work = force x distance

work = 600N x 10m

work = 6000 Joules

Therefore, the work done by the effort is 6000 Joules.
