Practical: Motorized gyroscope, Study of gyroscopic effect and couple.
Unit VI – Mechanical Vibrations
Vibrations-single degree of freedom system, equations of motion-undamped and damped free vibration of single degree of freedom system, logarithmic decrement, Forced vibration of single degree of freedom system, magnification factor, rotating unbalance-support harmonic excitation, critical speed of shafts
Practical: Undamped free vibrations of a single degree freedom spring-mass system. Torsional Vibration (Undamped) of single rotor shaft system Determination of critical speed of shafts.
Activities: Tasks T1. Design a four-bar mechanism for an application such as a windshield wiper or robotic arm to achieve a desired motion path. T2. Design a cam and follower system for an IC engine valve mechanism to achieve specified motion (displacement, velocity, acceleration). T3. Design a gear train system (simple or epicyclic) for an automobile gearbox or industrial machine to obtain required speed reduction and torque transmission. T4. Analyze and design a rotating system (shaft with masses) for proper balancing and determine the critical speed to avoid excessive vibration in machines (e.g., turbine shaft or motor rotor).
