The multiple vee-belt drive illustrated in Figure Q5(b), has a groove angle of 40° and is required to transmit 17.4 kW from a pulley 165 mm in diameter to another pulley 330 mm in diameter which rotates at 390 rev/min. The coefficient of friction between the belt and the pulleys is 0.32 and the maximum permissible belt tension is 550 N for each of the five belts used. For this geometry and conditions, calculate: i) the torque on the smaller pulley; ii) the angle of lap (es) required to achieve this power rating; the ideal centre distance (C) for this angle of lap. iii)

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.
