MECHANISMS
MECHANISMS
The sistern of gears with a chain for bicycles, the cogwheels of a clock, the lever of a seesaw, the pulley used to get water from a well are
some of the simplest mechanisms that are part of many mechanical
obiects.

GEAR TARIN
This is a system of more than two gears, connected together as
shown in the diagram.

CRANK-LINK-SLIDER
-
This rod has articulated lomts at each end — one is connected
to the crank and the inher to the slider.
-
Linear Motion Mechanisms
These transmit motion and force in a straight line from one point to another, for example, a lever or a pulley.
-
FIXED PULLEYS
A fixed pulley is a wheel that has a
groove for a rope, cham or belt to go round
it.
-
MOVEABLE PULLEYS
-
The effort needed to move a load with a
moveable pulley is half on the effort needed
with a fixed pulley.
-
COMPOUND PULLEYS
This is a set of fixed and moveable pulleys, often called a block and tackle.
ROTARY MOTION MECHANISMS
These transmit motion and effort in a circular wave from the imput to the output. Rotary motion mechamsms include friction drives, pulley systems, gears and worm gears.
