What is virtual or formative gear?   4. Describe the law of gearing. Why involute teeth are preferred over cycloidal teeth? What is the reason of interference in gears and how it can be avoided?  5. Using a suitable schematic diagram explain the forces acting on worm gears. Also, define normal pitch, helix angle and efficiency of worm gear drive.  6. Briefly discuss the following: (i) System of gear teeth (ii) Pressure angle  7. Discuss the classification of helical gears.  With a neat sketch explain the forces acting on a helical gear and explain.  8. With the help of a sketch, explain how an axial thrus...

1. Uniqueness in their study material: Study material provided by the coaching institutes is of little assistance if they are compact copy-paste or rewrite of materials taken from other books. If the reading of such material doesn’t increase interest and enjoyment then they are not worth it. There are plenty of standard books on each subject by good authors, which can make your study enjoyable during preparation. 2. Collection of quality books in their library: During the process of theory conceptualization and building application capabilities, you need good books, which can really put your brain on exercise. Check out their library! 3. Flexibility in the Coaching Model: What happens when your pace of learning is much faster or slower than the average? Is there any mechanism by which the model can identify exactly where you need help and provide the same? Is it possible in that coaching model to minimize the wastage of your time? 4. Quality of questions discussed: Number of questions...
