Q1. What is difference between first projection and third projection?
Ans. 
First projection is a front view of an object, while third projection is a side view.
• First projection shows the front view of an object, while third projection shows the side view.

• First projection is typically labeled as 'F' on engineering drawings, while third projection is labeled as 'T'.

• First projection is used to show the overall shape and size of an object, while third projection is used to show the depth and heig

Q5. Slenderness ratio and codes used
Ans. 
Slenderness ratio is a measure of a structural element's stability under compression, and codes such as ACI, AISC, and Eurocode are commonly used in design.
• Slenderness ratio is the ratio of the effective length of a column to its radius of gyration.

• Different codes have different criteria for slenderness ratio limits to ensure structural stability.

• Examples of codes used for slenderness ratio calculations include ACI (Am...read more

Q3. Types of transformers, basic principles of transformers working
Ans. 
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
• Transformers are of two types - step-up and step-down transformers

• The basic principle of transformer working is electromagnetic induction

• The transformer consists of two coils - primary and secondary

• When an alternating current flows through the primary coil, it creates a magnetic field which induces a v...read more

Q4. Working of induction motor
Ans. 
An induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
• Consists of a stator and a rotor

• Stator has a set of coils that produce a rotating magnetic field

• Rotor is made up of conductive bars and is placed inside the stator

• The rotating magnetic field induces a current in the rotor, which in turn produces a magnetic field

• The interaction between the two magne...read more
