A Junkyard crane lifts up metal and other scrap substances from the heaps of junk to either put it in the crusher or to place it somewhere else.
Both lifts and cranes are used for same purpose, which is load lifting. The difference between lift and crane is the way they lift load. Lifts carry weights from the bottom and move upwards while cranes pull weights from bottom to top.
The energy transformation that occurs when a person lifts a chair involves converting chemical energy from the food consumed into mechanical energy to move the muscles, which lifts the chair against the force of gravity.

The work done is 400 J. Work is equal to force multiplied by distance. In this case, the force is the weight of the block (100 N) and the distance is the change in height (4 m).
Boom: The long arm of the crane that extends and lifts objects. Hook: The attachment at the end of the crane’s cable that secures and lifts loads. Trolley: The mechanism that moves along the boom, allowing the hook to reach different points. Motor: Provides the power needed for the crane's operation. Counterweights: Balances the load being lifted, ensuring stability and safety.
