Question

Which of the following scenarios are the applications of an inclined plane?

• A. Ramp to load a truck with luggage.
• B. Elevator in a hospital.
• C. Winding road with subtle slope built around a hill.
• D. Gangplank used to unload the cargo of a ship.

Answer 1

Answer: (A), (C), (D)

The correct options are
A

Ramp to load a truck with luggage.

C

Winding road with subtle slope built around a hill.

D

Gangplank used to unload the cargo of a ship.

The effort used to push the load up in an inclined plane is less than the effort required to directly lift the load.
A coolie uses a ramp which serves as an inclined plane to load a truck with luggage.
A winding road with subtle slope is built around a hill. This reduces the power requirement of the vehicles to climb the hill slope.
Gangplank is provided at docks/ships to unload the cargo of a ship.
Whereas, elevator in the hospitals works on the principle of pulley system.
