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:

at pin joints. This is the relative angular velocity between two connected links multiplied by the radius of the pin: Theory Of Machines By Rs Khurmi Solution Manual Chapter 6

Some points are obvious, such as pin joints between two links. Kennedy's Theorem (Three Centres in a Line): cap N equals the fraction with numerator n

. 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) Kennedy's Theorem (Three Centres in a Line):

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

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