Level 6 Graduate Diploma in Engineering (9210-01) - City & Guilds

Range
Mechanism - is mechanical portion of the machine for transferring motion and forces from a power
source to an output.
Outcome 6 Explain the concepts of friction and friction devices.
The learner can:
1. Explain the friction phenomenon and laws of friction.
2. Analyse how belt and rope drives transmit power.
3. Analyse transmission of power through various types of friction clutches.
4. Explain power transmission through screw drives with square threads and V-threads.
5. Explain the theory of shoe, band and block brakes.
Outcome 7 Explain fundamental of vibration of rotating masses and the
need to balance rotating masses and determine unbalanced
forces of systems with rotating masses and balance them.
The learner can:
1. Explain the need to balance rotating parts; static and dynamic unbalance of rotating masses.
2. Solve balance problems of several masses in different planes through analytical and graphical
methods.
Range
Unbalance - vibratory force or motion on bearings due to centrifugal forces
Outcome 8 Explain the principles, and explain use and application of
different governors and cams.
The learner can:
1. Explain different types of governors and their distinct characteristics.
2. Explain the effect of friction, controlling force, governor effort and power, sensitivity and
isochronism.
3. Explain different types of cams and the function performed by them.
4. Design a cam profile to produce the required follower motion.
Outcome 9 Perceive vibration principles and develop skills in modelling
simple vibratory systems with first degree of vibration to
solvable models.
The learner can:
1. Explain the types of vibrations, basic features of vibration systems and degrees of freedom.
2. Explain natural frequency, and calculation of natural frequency of vibration.
3. Explain resonance phenomenon and its importance in engineering
4. Model simple vibratory systems to form a mathematically solvable system.
5. Develop skills to solve mathematical equations and to obtain system response in terms of
displacement, velocity and acceleration using both equilibrium and energy methods.
6. Explain damped and undamped vibrations and explain effect of damping.
7. Explain forced damped and undamped vibration and their impacts.
