CAM ANALYSIS APPARATUS
DESCRIPTION                                                                     
The setup is a motorized unit consisting of a camshaft 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. These are already hardened to reduce the wear. With the help of combination of provided cams and followers following experiments can be conducted: EXPERIMENTATION:
To plot the(Follower displacement Vs Angle of rotation) curves for different cam follower pairs
The follower bounce can be observed by using a stroboscope (Optional) & effect of follower weight on bounce can be studied.
To study the effect of follower weight on bounce.
To study the effect of spring compression on bounce.

WHIRLING OF SHAFT DEMONSTRATOR
 DESCRIPTION:                                                                    
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 can be 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.
EXPERIMENTATION:
Display of various modes of whirl for a shaft with
Both ends directionally fixed.
One ends fixed and other free
Both ends directionally free.
Modes of vibrations can be studied and frequency can be measured in each case.
UTILITIES REQUIRED
Floor area of 2m x 0.5 m.
Electricity Supply 230 V AC Single Phase 0.5 kW.
Digital Tachometer

Supplied with a speed control unit.
Instruction Manual an ENGLISH instruction manual will be provided along with the Apparatus

STATIC & DYNAMIC BALANCING DEMONSTRATOR
DESCRIPTION:
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.
EXPERIMENTATION:
To balance the masses statically and dynamically of a single rotating mass system.
To observation of effect of unbalance in a rotating mass system.
UTILITIES REQUIRED
Electricity Supply: 220 V AC Single Phase 0.5 kW with earth
Floor Area 0.5m x 0.5m
Digital Tachometer
TECHNICAL DETAILS
Drive Motor FHP Motor, variable speed, with speed controller.
Balancing weight 4 Nos. of Stainless Steel with different sized eccentric mass for varying unbalances.
Rotating Shaft Material Stainless Steel
Instruction Manual An ENGLISH instruction manual will be provided along With the Apparatus.

MOTORIZED GYROSCOPE APPARATUS
 DESCRIPTION:
The set up consists of stainless steel disc mounted on a horizontal shaft, rotated by a variable speed motor.  The rotor shaft is 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 can be applied by calculating the weight and distance of weight from the centre of rotor.  The gyroscopic couple can be determined.
EXPERIMENTATION:
Experimental justification of the equation T = I p. for calculating the gyroscopic couple by observation and measurement of results for  independent vibrations in applied couple T and precession  p.
To study the gyroscopic effect of a rotating disc.
