Observation of Gyroscope behavior (Two Laws of Stability)
Experimental justification of the equation T= I. W. Wp
For all types of Governor.
Hartnell Governors. Effect of varying the spring
For the combination of cams and followers provided, the following tests can be conducted.
Simple Demonstrations : Observation of the pressure profile at the various conditions of load and speed.
Experimental Investigation : After noting the pressure profile for any chosen conditions the following analysis may be conducted.
a) Plotting the Cartesian and polar pressure curves.
b) Plotting the theoretical Summer field curves.
This board illustrates the process of cutting of Involutes Gear Teeth, by use of rack type cutter. It consists of three transparent discs A, B, C having pitch circle diameters 192, 225, 306 mm respectively. A Gear tooth profile with module 18 mm can be traced out on piece of paper placed between disc & cutter. An effect of interference & undercutting on correct profile of gear tooth can be studied from the profiles traced.
