Introduction
The Theory of Machines is concerned with the Motion of parts of machines and the forces which act on those parts. In most cases these forces are not constant and their calculation demands that we know the velocities and accelerations which occur in the various components.
The concept of Instantaneous Centres of Velocity was covered in the section on Mechanisms. In this section the Analysis of Velocity and Acceleration are considered with particular reference to Cranks and Pistons.
PISTON MOTION, VELOCITY AND ACCELERATION
Figure 1. Inline - The cylinders are arranged in a line in a single bank.
Figure 2. V - The cylinders are arranged in two banks set at an angle to one another.
Figure 3. Flat - The cylinders are arranged in two banks on opposite sides of the engine.
