- Q2. What is relay and type?
- Ans.
A relay is an electrically operated switch that uses an electromagnet to mechanically control the switching action.
Relays are used to control high power or high voltage circuits with a low power signal.
They can be classified into different types based on their construction and operation, such as electromagnetic relays, solid-state relays, thermal relays, etc.
Electromagnetic relays use an electromagnet to control the sw...
- Q3. What is motors and its types?
- Ans.
Motors are devices that convert electrical energy into mechanical energy. There are various types of motors.
DC motors convert electrical energy into mechanical energy using a magnetic field. They are commonly used in household appliances.
AC motors are used in industrial applications and are more efficient than DC motors.
Stepper motors are used in robotics and automation as they can move in precise steps.
Servo motors ar...
- Q4. We know there are generally two types of motors, AC motor, and DC motor. AC motors are flexible for speed control and demand low power during start. On the other hand, DC motors are widely used due to its ...
- Q5. What is difference between AC& DC current?
- Ans.
AC current changes direction periodically while DC current flows in one direction only.
AC current is used for power transmission over long distances while DC current is used for electronic devices.
AC current can be easily transformed into different voltage levels using transformers while DC current cannot.
AC current is more dangerous to humans than DC current at the same voltage level.
Examples of AC devices include air...
- Q6. Electric current flows in two ways as an alternating current (AC) or direct current (DC). The main difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow ...
- Ans.
AC and DC differ in the direction of electron flow. DC flows steadily in one direction while AC switches direction.
AC stands for alternating current while DC stands for direct current
AC is commonly used in household appliances while DC is used in batteries and electronic devices
AC can travel long distances without losing much energy while DC cannot
Examples of AC sources include power grids and generators while examples

- Q1. What is beam and it's shear force unit
- Ans.
A beam is a structural element that carries load primarily in bending. The shear force unit is measured in Newtons (N) or pounds-force (lbf).
A beam is a long, horizontal structural member that supports loads by resisting bending.
Shear force is the force that acts parallel to the cross-section of the beam.
The unit of shear force is typically measured in Newtons (N) or pounds-force (lbf).
(1 Question)
- Q1. What is moment of interia
- Ans.
Moment of inertia is a measure of an object's resistance to changes in its rotation.
Moment of inertia depends on the mass distribution of an object.
It is calculated by summing the products of the mass of each particle and the square of its distance from the axis of rotation.
Moment of inertia is denoted by the symbol 'I'.
For example, a solid sphere has a higher moment of inertia compared to a hollow sphere of the same m
