## THEORY OF MACHINE LABS

### DOM-107 UNIVERSAL GOVERNOR APPARATUS

The set-up is designed to study the working of different governors normally used to control the speed. It consists of a main spindle, mounted vertically on the base plate. This spindle is driven by a variable speed Motor which is also mounted vertically on the same base plate. One governor assembly out of four can be mounted on spindle. The spindle speed is controlled by speed control unit. A graduated scale is fitted to the sleeve to measure the displacement.

### DOM-400 HOOKE'S LAW APPARATUS

Hooke’s law describe the elastic behavior of components where deformation is proportional to the load acting upon them. This behavior is typical for metal under light loads. It demonstrate the application of Hooke's law and shows the deformation of tension springs under load. For this purpose, a spring is suspended from a stand and loaded down by a weight. The elongation is road-off directly from a scale. As a linear relationship is shown between the active force and the elongation of the spring. Hooke’s law can be applied.

### DOM-106 JOURNAL BEARING APPARATUS

The apparatus consists of a plain steel shaft excavated in a bearing and directly driven by a FHP Motor. The bearing is freely supported on the shaft and sealed at the motor end. The speed of the motor is controlled by the speed control unit. One compound pressure gauge is mounted on Bearing to measure the pressure at different position around the circumference. Bearing are free to rotate and can be adjusted at any position of circular scale. The bearing are loaded by attaching weights to the arm supported beneath it.

### DOM-105 MOTORISED GYROSCOPE with S.S Disc

The set up consists of stainless steel disc mounted on a horizontal shaft, rotated by a variable speed motor. The rotor shaft coupled to a motor mounted on a trunion frame having bearings in a yoke frame, which is free to rotate about vertical axis. A weight pan on other side of disc balances the weight of motor. Rotor disc can be move about three axis. Torque applied by calculating the weight and distance of weight from the center of rotor. The gyroscopic couple can be determined.

### DOM-104 STATIC & DYNAMIC BALANCING DEMONSTRATOR

This equipment is designed for carrying out the experiment for balancing a rotation mass system. The apparatus consists of a stainless steel shaft fixed in a rectangular frame. A set of four blocks with a clamping arrangement is provided. For static balancing, each block is individually clamped on shaft. For dynamic balancing, a moment polygon is drawn using relative weights and angular and axial position of blocks is determined. The block are clamped on shaft is rotated by a motor to check dynamic balance of the system. The system is provided with angular scale and is suspended with chains for dynamic balancing.

### DOM-103 WHIRLING OF SHAFT DEMONSTRATOR

The set up is designed to study the whirling of shafts. The set-up consists of a sturdy frame, bearing holders, variable speed motor etc. to drive the shaft along with speed control unit. Different bearing fitted in bearing block to have different end conditions i.e. (i) both end fixed,
(ii) one end free and one end fixed etc. As the test is destructive, hence the shaft can not be used again.

### DOM-102 CAM ANALYSIS APPARATUS

The Setup is a motorized unit consisting of a cam shaft driven by a variable speed motor. The free end of the camshaft has a facility to mount the cam easily.The follower is properly guided in gunmetal bushes and the type of follower can be changed according to the cam under test, graduated circular protractor is fitted co-axial with the shaft and dial gauge fitted on the follower shaft, is used to note the follower displacement for the angle of cam rotation. A spring is used to provide controlling force to the follower system. Weights on the follower shaft can be adjusted as per the requirement. An arrangement is provided to regulate the speed. The apparatus is very useful for testing the cam performance for jump phenomenon during operation and the effect of change of inertia forces on jump action of cam-follower during operation can be observed. Three sets of cams and followers are supplied with the apparatus. Theses are already hardened to reduce the wear.

### DOM-101 UNIVERSAL VIBRATION APPARATUS

The apparatus is comprehensive unit to perform the vibration experiments. A universal frame is provided upon which quick and easy assembly of various experiments can be done. The unit is self-contained to safely store spares. The students can easily assemble the experiments and study the theory of vibrations practically.

### Deflection of Beam Apparatus ST-101M

Bench mounted apparatus  Consists of a rigid frame approximately 1.15m long with a 1m scale fitted to the front.  The mm division scale is used to indicate the support positions and measure their spacing.  The knife edge and built-in supports are positioned anywhere along the frame.  A range of test beams is loaded by upto three hangers and stirrup units whilst deflections are measure by dial indicators reading to 0,01mm.  A slope indicator is attached to the test beam as required and a position indicator is used to determine the location of the load hangers.

### Equilibrium of Moment on Two Arm Lever ST-107 M

The apparatus is used to investigate the fundamentals of the equilibrium of moments based on the example of a two-arm lever. Moments occurring on the lever are to be brought to equilibrium. A centrally mounted beam represents a two-arm lever. Movable riders are placed on the lever and loads are applied by means of weight. Equilibrium is attained by moving the loads. Distances from the pivot pointthe lever arms- can be read from an integrated scale. The calculation of the lever arms is verified in the experiment. A vertical column carriers the lever. A sturdy base plate is ensure that the unit stands securely.
