Drum Brake Apparatus |
Ref 1.12 |
| The Sanderson Drum Brake Apparatus provides a means of demonstrating the difference in braking torque between leading and trailing shoe braking systems. With two shoes linked together, the self energising action can be demonstrated. The apparatus may be used to investigate the relationship between actuating forces and the braking torques and for the determination of the co-effecient of friction between the brake lining and the drum. |

Acceleration of Geared Systems |
Ref 4.15 |
| The Sanderson Acceleration of Geared Systems consists of three shafts, each mounted on ball races, supported in a suitable frame and connected by gearing. Gear ratios can be changed and gears of suitable sizes are provided. A flywheel is attached to one of the shafts. discs of varying mass moments of inertia can be attached to the other two shafts. A torque drum is secured to each shaft. By allowing a mass, attached to the drum, to fall the acceleration of the system can be calculated. |
