Please explain the mechanism
Answers
Explanation:
In the science of biology, a mechanism is a system of causally interacting parts and processes that produce one or more effects.[1] Scientists explain phenomena by describing mechanisms that could produce the phenomena. For example, natural selection is a mechanism of biological evolution; other mechanisms of evolution include genetic drift, mutation, and gene flow. In ecology, mechanisms such as predation and host-parasite interactions produce change in ecological systems.
In engineering, a mechanism is a device that transforms input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components that can include:
Gears and gear trains
Belt and chain drives
Cam and followers
Linkage
Friction devices, such as brakes and clutches
Structural components such as a frame, fasteners, bearings, springs, lubricants
Various machine elements, such as splines, pins, and keys.
