Speed is the rate of change of distance while velocity is the rate of change of displacement.
Speed is a scalar quantity while velocity is a vector quantity.
Speed can be calculated by dividing distance by time while velocity can be calculated by dividing displacement by time.
Speed has no direction while velocity has direction.
For example, a car moving at a constant speed of 60 km/h has a speed of 60 km/h but its velocit...
Moment of inertia is the measure of an object's resistance to rotational motion.
Moment of inertia depends on the mass and distribution of mass of an object.
It is denoted by the symbol 'I'.
It is used to calculate the torque required to rotate an object.
Examples include a spinning top and a rotating wheel.
Moment of inertia is important in engineering and physics applications.
Petrol in a diesel engine can cause serious damage to the engine.
Petrol does not ignite in the same way as diesel, causing incomplete combustion and damage to the engine.
The engine may start to make unusual noises and vibrations.
The fuel injectors and fuel pump may also be damaged.
It is important to drain the fuel tank and flush the fuel system as soon as possible.
Prevention is key - always double-check the fuel type b

An ideal diode is a theoretical diode that exhibits zero voltage drop when forward biased and infinite resistance when reverse biased.
An ideal diode acts as a perfect conductor when forward biased.
It allows current to flow in one direction with zero voltage drop.
When reverse biased, it acts as an open circuit with infinite resistance.
The input-output characteristic curve of an ideal diode is a vertical line at zero vol...
Program to compute factorial of a number using recursion
Define a function that takes a number as input
Check if the number is 0 or 1, return 1 if true
Else, call the function recursively with n-1 as input and multiply with n
Return the result
Example: factorial(5) = 5 * factorial(4) = 5 * 4 * factorial(3) = 5 * 4 * 3 * factorial(2) = 5 * 4 * 3 * 2 * factorial(1) = 5 * 4 * 3 * 2 * 1 = 120

The OSI model has 7 layers that define how data is transmitted over a network.
Layer 1: Physical - deals with the physical connection of devices
Layer 2: Data Link - responsible for error-free transfer of data between devices
Layer 3: Network - handles routing of data between different networks
Layer 4: Transport - ensures reliable delivery of data between applications
Layer 5: Session - establishes and manages connections ...
Session layer manages and controls the connections between applications.
Establishes, maintains and terminates sessions between applications
Synchronizes data exchange between applications
Manages session checkpoints and recovery
Examples: Telnet, FTP, SMTP
A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage is reached.
Zener diodes are commonly used as voltage regulators.
They have a sharp breakdown voltage, which makes them useful for stabilizing voltage in electronic circuits.
Zener diodes are often used in power supplies, voltage references, and surge protectors.
They are also used in noise reduction circuits and as...

An IP address is a unique numerical identifier assigned to every device connected to the internet.
IP stands for Internet Protocol
It consists of four sets of numbers separated by dots
Each set can range from 0 to 255
Example: 192.168.1.1 is an IP address
IPv4 and IPv6 are the two versions of IP addresses
DRDO stands for Defense Research and Development Organization and NASA stands for National Aeronautics and Space Administration.
DRDO is an agency of the Government of India, responsible for the development of technology for use by the military.

A lance is a long, pointed weapon used in medieval warfare.
Lances were typically made of wood or metal.
They were used by knights on horseback to charge at their enemies.
The length of a lance varied, but it was usually between 9 and 14 feet long.
Lances were often decorated with banners or flags to identify the knight carrying it.
The use of lances declined with the advent of firearms in warfare.
Tilt drive is a mechanism used in construction to tilt heavy objects or structures.
Tilt drive is commonly used in the construction of bridges, buildings, and large machinery.
It involves the use of hydraulic cylinders or motors to tilt the object or structure.
The tilt drive system must be carefully designed and engineered to ensure safety and stability.
Proper maintenance and inspection of the tilt drive system is crucia...
ID fan stands for Induced Draft fan which is used to create negative pressure in a boiler.
ID fan is used to draw flue gases from the furnace and exhaust them to the atmosphere.
It helps in maintaining the proper flow of air and gases in the boiler.
ID fan is typically installed at the outlet of the boiler.
It is driven by an electric motor or steam turbine.
The size and capacity of ID fan depend on the size of the boiler a...
Bernoulli theorem is a principle that describes the relationship between fluid speed and pressure.
States that as the speed of a fluid increases, the pressure within the fluid decreases
Used to explain the lift force generated by an airplane wing
Applicable to both incompressible and compressible fluids
Bearings are used to reduce friction between two moving parts. There are different types of bearings and each requires specific maintenance.
Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.
Ball bearings are the most common type and require regular lubrication.
Roller bearings are used for heavy loads and require periodic cleaning and lubrication.
Plain bearings are simple and r...
Design of gears involves selecting appropriate gear type, size, material, and tooth profile for efficient power transmission.
Gears are used to transmit power and motion between two rotating shafts.
The gear type and size are selected based on the required speed ratio and torque.

The tooth profile is designed to ensure smooth and efficient power tr...
Bearings are mechanical components that reduce friction between moving parts and support axial and radial loads.
Bearings work by allowing two surfaces to roll or slide over each other with minimal friction.
They are designed to support loads in a specific direction, such as radial or axial.
There are several types of bearings, including ball bearings, roller bearings, and plain bearings.
Ball bearings use balls to reduce ...
