1. Define spur gear.
A spur gear is a cylindrical gear whose tooth traces are straight line generation of the reference cylinder. They are used to transmit rotary motion between parallel shafts.
2. Define addendum and dedendum.
Addendum is the radial distance of a tooth from the pitch circle to the top of the tooth. Dedendum is the radial distance of a tooth from the pitch circle to the bottom of the tooth.
3. Define circular pitch.
It is the distance measured on the circumference of the pitch circle from a point of one
tooth to the corresponding point on the next tooth. It is denoted by Pc
Circular pitch Pc= P/DT Where D = Diameter of pitch circle. T = Number of teeth on the wheel.
4. Define I) path of contact. II) Length of path of contact.
Path of contact: It is the path traced by the point of contact of two teeth from the beginning to the end of engagement.
Length of path of contact: It is the length of common normal cut- off by the addendum circles of the wheel and pinion.
5. State the law of gearing.
Law of gearing states that, the common normal at the point of contact between a pair of teeth must always pass through the pitch point.
6.A training program for school children named 'Yuvika' is being conducted by which Indian organization?
The Indian Space Research Organization is set to conduct the second session of its Young Scientist Programme for school children called YuvaVigyaniKaryakram (YUVIKA).
7.National Education Policy 2020 emphasizes to set up which fund?
National Education Policy (NEP) 2020 emphasizes setting up of Gender Inclusion Fund, Special Education Zones for disadvantaged regions and groups.
8.Which organisation has launched the CollabCAD software to provide a total engineering solution for students?
The National Informatics Centre and Central Board of Secondary Education has launched the CollabCAD Software to provide a total engineering solution for students and Faculty of Engineering Graphics Curriculum.
9.Which e-learning platform has been featured in Time Magazine's 2021 list of 100 most influential companies?
Two Indian firms, the Reliance's Jio Platforms and e-learning startup Byju's have been featured in Time Magazine's 2021 list of 100 most influential companies.
10.How will the business make money?
There was even a time, in the early days of the online world, when people dismissed the very notion of a business model as something from the old economy.

12.What are the biggest challenges you face in business?
Every business faces challenges, especially in competitive markets or with technological change. Your business plan should describe in detail the particular challenges you face and how you plan to overcome them. The challenges can be part of the business environment you compete in — a crowded field of competitors or regulatory uncertainties, for example. But some of the challenges you face are also likely to be related specifically to your company, such as hiring and holding on to skilled employees, for instance, or responding quickly to changes in the marketplace.
13.Why do we need Artificial Intelligence?
The goal of Artificial intelligence is to create intelligent machines that can mimic human behavior. We need AI for today's world to solve complex problems, make our lives more smoothly by automating the routine work, saving the manpower, and to perform many more other tasks.
14. How is machine learning related to AI?
Machine learning is a subset or subfield of Artificial intelligence. It is a way of achieving AI. As both are the two different concepts and the relation between both can be understood as "AI uses different Machine learning algorithms and concepts to solve the complex problems."
15. Give a brief introduction to the Turing test in AI?
Turing test is one of the popular intelligence tests in Artificial intelligence. The Turing test was introduced by Alan Turing in the year 1950. It is a test to determine that if a machine can think like a human or not. According to this test, a computer can only be said to be intelligent if it can mimic human responses under some particular conditions.
