To solve any problem in this chapter, you must first determine how many I-centres exist for the given mechanism. For a mechanism with links, the number of I-centres ( ) is calculated using the formula:

A common advanced problem in this chapter involves finding the rubbing velocity

. This chapter is a cornerstone of kinematic analysis, moving beyond basic displacements to determine how fast parts of a machine are moving at any given "instant". Instantaneous Centre (I-centre) Theory Of Machines By Rs Khurmi Solution Manual Chapter 6

cap N equals the fraction with numerator n open paren n minus 1 close paren and denominator 2 end-fraction 2. Locate the I-Centres I-centres are located using two main approaches: By Inspection:

Some points are obvious, such as pin joints between two links. Kennedy's Theorem (Three Centres in a Line): Instantaneous Centre (I-centre) from this chapter, such as

at pin joints. This is the relative angular velocity between two connected links multiplied by the radius of the pin:

provides the analytical and graphical tools needed to solve for the velocities of various links Instantaneous Centre Method Are you working on a specific problem

This rule states that if three bodies move relative to each other, their three relative instantaneous centres must lie on a straight line. This is the primary tool for finding "hidden" or virtual centres. 3. Calculate Linear and Angular Velocity

In RS Khurmi’s Theory of Machines focuses on Velocity in Mechanisms (Instantaneous Centre Method)
