Suggested Practicals/ Exercises
The practicals in this section are PrOs ( i . e sub-components of the COs) to be developed and assessed in the student for the attainment of the competency
Practical Outcomes (PrOs)
- Use Differential axle and wheel.
- Identify various equipment related to Applied Mechanics.
- Use Simple screw jack.
- Use worm and worm wheel.
- Use single or double purchase crab
- Use Westons differential or wormed geared pullet block.

- Determine centroid of geometrical plane figures
Note
- A suggestive list of PrOs is given in the above table. More such PrOs can be added to attain the COs and competency. A judicial mix of minimum 12 or more practical need to be performed, out of which the practicals marked as are compulsory, so that the student reaches the ‘Precision Level’ of Dave’s ‘Psychomotor Domain Taxonomy’ as generally required by the industry.
- The ‘Process’ and ‘Product’ related skills associated with each PrO is to be assessed according to a suggested sample given below:
Performance Indicators Weightage in %
- Preparation o: experimental set up 20%
- Setting and operation 20%
- Safety measures 10%
- Observations and Recording 10%
- Interpretation of result and Conclusion 20%
- Answer to sample questions 10%
- Submission report in time 10% Total 100
The above PrOs also comprise of the following social skills/attitudes which are Affective Domain Outcomes (ADOs) that are best developed experiences:
- Follow safety practices
- Practice good housekeeping.C. Demonstrate working as a leader/a team member
- Maintain tools and equipment.
- Follow ethical practices.
The ADOs are not specific to any one PrO, but are embedded in many PrOs. Hence, the acquisition of the ADOs takes place gradually in the student when s/he undertakes a series of practical experiences over a period of time Moreover, the level of achievement of the ADOs according to Krathwohls Affective Domain Taxonomy’ should gradually increase as planned below:
- ‘Valuing Level in 1st year
- ‘Organising Level in 2″d year
- ‘Characterising Level” in 3rd year
