Define a machine in terms of its basic objective.
A device to transfer load to source
A device to transfer and transform
motion and force from source to load
A device to transform force
A device used to transfer force
A device to transfer and transform
motion and force from source to load
●A device to transfer and transform
motion and force from source to load is the basic objective of a machine.
●A simple machine is a mechanical
device that changes the direction or magnitude of a force.
●They can be defined as the simplest
mechanisms that use mechanical advantages (leverage) to multiply force.
Hence, the correct option is (B).
