A block and tackle system of pulleys consisting of 4 pulleys is used to raise a load 500n through a height of 20m if the total work done against equivalent to 800j calculate the work done by the effort
To calculate the work done by the effort, we need to use the formula:
Work = Force × Distance
Given that the load is raised through a height of 20m and the total work done against is equivalent to 800J, we can calculate the force applied by the effort.
Work = Force × Distance
800J = Force × 20m
To find the force, rearrange the equation:
Force = 800J / 20m
Force = 40N
Now, we can calculate the work done by the effort.
Work = Force × Distance
Work = 40N × 20m
Work = 800J
Therefore, the work done by the effort is 800J.
