What Are Linkages and Levers

A linkage or linked lever system is a number of levers that are joined together. They are connected by means of a pivot, which can be either a fixed or a moving pivot. A linkage is designed to change the direction of force and movement. A fixed pivot turns around one point and cannot move away from this position.

What is the difference between levers and linkages?

With a class 3 lever, the pivot is at one end, the load is at the other and the effort is in the middle. A linkage is a mechanism made by connecting together levers. rivets etc. more things move at the same time.

How do levers and linkages work?

Many mechanisms take one type of input motion, and output it as a different type of motion. In a lever and linkage mechanism, the ‘input’ is where the user pushes or pulls a card strip. The ‘output’ is where one or more parts of the picture move. When you push the linkage (input), it moves the two levers (output).
