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:

is a point, common to two bodies, that has the same velocity in each body. At a specific moment, the bodies behave as if they are rotating around this point relative to one another. 1. Identify the Number of Instantaneous Centres Theory Of Machines By Rs Khurmi Solution Manual Chapter 6

. 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)

Once the necessary I-centres are located, you can find the velocity of any point. The fundamental relationship used is: v equals omega center dot r is the linear velocity of a point. is the angular velocity of the link. is the distance from the point to the relevant I-centre. 4. Solve for Rubbing Velocity from this chapter, such as a four-bar linkage

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:

A common advanced problem in this chapter involves finding the rubbing velocity At a specific moment, the bodies behave as

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