A kinematic joint is a connection between two or more links, which allows some motion, or potential motion, between the connected links. Depending upon the number of links at the joint, a joint can be binary, ternary or quaternary. The

## Links, Joints, and Kinematic Pairs

Links: A link, is an (assumed) rigid body which possesses at least two nodes which are points for attachment to other links. Binary Link: This link has two nodes. Ternary Link: This link has three nodes. Quaternary Link: This link has four nodes. Joints: A

## Velocity Analysis – Slider Crank Mechanism (Graphical Method)

Consider a slider crank mechanism as shown: > The crank OA is moving with uniform angular velocity ω radians/second in the counter-clockwise direction. > At point B, the slider moves on the fixed guide G. > AB is the coupler joining A and B. We

## Ratchet and Pawl Mechanism

Ratchet and Pawl mechanism is a type of intermittent motion mechanism. It allows the rotation of the shaft in one direction only and prevents its motion in the other direction. It consists of an arm that pivots about the center

## Double Crank Mechanism

Double Crank Mechanism is a four bar linkage. In this linkage, both the links pivoted to the fixed link rotates fully. It is a Grashof linkage for which the sum of the lengths of the shortest link and the largest

## Crank Rocker Mechanism

Crank Rocker Mechanism is a four bar linkage. In this linkage, the shortest link rotates fully while the other link pivoted to the fixed link oscillates. It is a Grashof linkage for which the sum of the lengths of the

## Vertical Line Test for Functions

Vertical Line Test for a Function: Not every curve in the coordinate plane can be the graph of a function. Using vertical line test, we can figure out whether a given curve is the graph of a function or not.

## Singleton Sets

A singleton set is the one which contains only one element. Let’s see a few examples of singleton sets: 1. Set of all even prime numbers: {2} Since 2 is the only even prime number, this set has only one

## Why are even functions called ‘even’, and odd functions called ‘odd’?

Why are even functions called ‘even’, and odd functions called ‘odd’? A function is an even function of if odd function of if for every in the function’s domain. The names even and odd comes from the powers of .

## What is a Mechanism?

What is a mechanism? A mechanism is a combination of a number of bodies assembled in such a way that the motion of one causes constrained and predictable motion to the others. The purpose of mechanism is to transform motion
