Universal Governor Apparatus
The set up consists of a small electric motor connected bevel reduction gear box or belt and pulley system through a flexible coupling. The Governor spindle is driven by a solid coupling connected to the gear box output shaft and is supported on ball bearing. The optional governor mechanism can be mounted on spindle. Speed control unit is provided to regulate speed and extension to the spindle shaft can be sued to use hand tachometer. The center sleeve to the porter and proell governors incorporates a weight sleeve to which weights are added. The Hartnell Governor can be operated as a stable or unstable Governor. The following range of experiments can be
Performed:

Static And Dynamic Balancing Apparatus
This is suitable for conducting experiments on static balancing and dynamic balancing with different weights. This consists of rectangular frame of steel perfectly balance with four different blocks. A protractor scale of the disc is provided to reach exact angular position of each weight to be measured. A linear scale provided below the frame provides the measurement of each weight along the shaft. The unit is hanging from a rigid steel frame through chain for dynamic balancing and can be fixed rigidly for static balancing.specified in the IS 2386 (Part I).


Cam Analysis Apparatus
The machine facilitates the study of dynamic behavior of cam follower. It consists of a DC Motor coupled to an extension shaft whose and carries a cam. A cam follower, mounted on the end of a vertical bar, is loaded on the cam face by compression spring is retained by a cross bar mounted on two vertical pillars attached to the base plate. Facility is provided to vary the pre compression of spring. The inertia of follower can be altered using weights.
Note:
Motor is provided only to demonstrate the actual water of system. However while drawing the graph the motor shall be rotated by hand only.


Motorized Gyroscope
This is to demonstrate the relationship between applied torque and the rate and direction of rotation. This is motorized and mounted on a frame such that free to rotate about three perpendicular axis. This facilitates to observe the laws of stability and justification of equation.








Whirling Of Shaft Apparatus
This compact and simple apparatus incorporated two features. Firstly, kinematics coupling at the driven and of the shaft to slide freely in longitudinal direction while revolving readily. The directional clamping of this end of the shaft is achieved by and interchangeable chuck without self aligning radial ball bearing.

The shaft is driven through a dynamically balanced flexible coupling by a universal motor, the speed of which can be controlled by a control unit. The speed of rotation of the shaft can be measured by a stroboscope. Tachometer can be also used for speed measurement. The following shafts made from steel will be supplied.
