Hint:A pulley system is a freight lift system that allows objects to be hoisted to higher floors. The pulley mechanism is used for Wells to hoist the bucket out of the well. In order to operate, certain forms of gym equipment use pulleys. In order to lift and position heavy goods, building pulleys are used.
Complete answer:
The pulley allows us, when we stand more or less erect, to pull at a convenient angle. We would be bent over at an angle that could hurt our back, to raise the bucket up with no pulley, which would make the lift more challenging.
Using a simple pulley confers no mechanical benefit, because with or without the pulley, the person drawing the water will have to apply the same force on the rope.But it changes the course needed. Whereas an upward force is needed to lift the bucket, using a pulley shifts the required force downwards.
It is better to exert downward pressures, so humans can use their body weight to draw up particularly heavy loads. On the other hand, imagine the biceps that somebody will use to raise a huge bucket full of hundreds of feet of water.
Hence, option C and D is correct.
Note:So in short we can say that drawing from a well with a pulley is simple because it helps to adjust the orientation of the force applied. This, in essence, makes moving the object quick. The pulley helps to raise the bucket full of water upwards in this situation.
