What is the minimum effort force required to lift a mass of 5kg buket in a pulley
To determine the minimum effort force required to lift a 5kg bucket using a pulley, we need to understand the concept of mechanical advantage. Mechanical advantage is the ratio of the output force (the force needed to lift the load) to the input force (the effort force applied).
In a simple pulley system, there are two types of configurations: a single fixed pulley and a moveable pulley (also known as a block and tackle system). Let's assume we are using a moveable pulley system.
The mechanical advantage of a moveable pulley system is equal to the number of supporting ropes attached to the moveable pulley. In this case, it is two, as there are two ropes supporting the moveable pulley. Therefore, the mechanical advantage is 2.
Now, to calculate the minimum effort force required, we divide the weight of the load (in this case, the 5kg bucket) by the mechanical advantage.
Minimum effort force = Weight of the load / Mechanical advantage
= 5kg / 2
= 2.5kg
So, the minimum effort force required to lift the 5kg bucket using a moveable pulley system is approximately 2.5kg.
