power assist
Strength-multiplying mechanism help
Power assist is a mechanism that uses hydraulic, electric, or mechanical force to reduce the physical effort needed for an operation.
Most commonly applied to steering and braking in vehicles: power-assisted steering makes parallel parking easier.
The term appears wherever human input is amplified by auxiliary force—wheelchairs, bicycle motors, industrial equipment.
