Does 01 year apprenticeship training will count as a work experience? I know, many student have this doubt that whether apprenticeship training will count as a work experience or not ? and it should be. So let me tell you today and clear your doubt about apprenticeship training count as a work experience . W ell, when I also completed my apprenticeship training, I had also this doubt in my mind. Then I searched and read about it many places and finally I got the proof of apprenticeship training will count as a work experience. My finally answer is YES apprenticeship training will count or consider as a work experien ce. I share with you the proof this.

Question Bank Mechanics of Solid (TORSION)
1. Define Torsion
- When a pair of forces of equal magnitude but opposite directions acting on body, it tends to twist the body.
- It is known as twisting moment or torsion moment or simply as torque.
- Torque is equal to the product of the force applied and the distance between the point of application of the force and the axis of the shaft.
2. What are the assumptions made in Torsion equation
- The material of the shaft is homogeneous.
- Perfectly elastic and obeys Hooke's law.
- Twist is uniform along the length of the shaft
- The stress does not exceed the limit of proportionality
- The shaft circular in section remains circular after loading
- Strain and deformations are small.
3. Why hollow circular shafts are preferred when compared to solid circular shafts?
- The torque transmitted by the hollow shaft is greater than the solid shaft.
- For same material, length and given torque, the weight of the hollow shaft will be less compared to solid shaft.
4.The expression for power transmitted by a shaft
P=2Ï€NT/60
Where,
N-speed in rpm
T-torque
5. Define torsional rigidity
- The torque required to introduce unit angle of twist in unit length is called torsional rigidity or stiffness of shaft.
6. What is composite shaft?
- Sometimes a shaft is made up of composite section i.e. one type of shaft is sleeved over other types of shaft. At the time of sleeving, the two shafts are joined together, that the composite shaft behaves like a single shaft.
7. What is a spring?
- A spring is an elastic member, which deflects, or distorts under the action of load and regains its original shape after the load is removed.
8. State functions of springs
- To measure forces in spring balance, meters and engine indicators.
- To store energy
9. What are the various types of springs?
- Helical springs
- Spiral springs
- Leaf springs
- Disc spring or Belleville springs
10. Types of the helical springs.
- Close- coiled or tension helical spring.
- Open -coiled or compression helical spring.
11.What is spring index?
- The ratio of mean or pitch diameter to the diameter of wire for the spring is called the spring index.
- it is denoted by (C).
12. What is solid length?
- The length of a spring under the maximum compression is called its solid length.
- It is the product of total number of coils and the diameter of wire.
13. Define Polar Modulus
- Polar modulus is defined as the ratio of polar moment of inertia to extreme radial distance of the fiber from the Centre.
