## Where is Peaucellier mechanism used?

Abstract: A straight line motion is a common application in engineering design and manufacture. The Peaucellier mechanism generates exact straight lines, meeting some restrictions among their links dimensions and the input angle.

### What is an exact straight line mechanism?

Explanation: The given straight line mechanism is called Watt’s mechanism. It consists of three links. Two of them are of equal length whereas one is shorter. Due to the rotation motion of the longer links, the centre of the shorter link traces an approximate straight line.

#### What is a linkage mechanism?

Linkage, in mechanical engineering, a system of solid, usually metallic, links (bars) connected to two or more other links by pin joints (hinges), sliding joints, or ball-and-socket joints so as to form a closed chain or a series of closed chains.

Which of these mechanism has eight links?

An eight-bar linkage is a one degree-of-freedom mechanism that is constructed from eight links and 10 joints. These linkages are rare compared to four-bar and six-bar linkages, but two well-known examples are the Peaucellier linkage and the linkage designed by Theo Jansen for his walking machines.

What is crank and slider used for?

A crank and slider mechanism will convert a rotary motion and force into reciprocating motion and force. A crank and slider mechanism will convert a reciprocating motion and force into rotary motion and force.

## What kind of contact can be established for a lower pair?

Lower pair: When the two elements of a pair have a surface contact when relative motion takes place and the surface of one element slides over the surface of the other, the pair formed is known as lower pair. Sliding pairs, turning pairs and screw pairs are the examples of lower pairs.
