Program to count number of 1s in binary representation of a number and demonstrate pointer concept.

• Use bitwise AND operator to check if the rightmost bit is 1

• Shift the number to the right by 1 bit after each check

• Use a pointer to access the memory address of a variable

• Dereference a pointer to access the value stored in that memory address

Petrol engines use spark ignition while diesel engines use compression ignition.

• Petrol engines use spark plugs to ignite the fuel-air mixture, while diesel engines rely on compression to ignite the fuel.

• Petrol engines typically have higher RPM (revolutions per minute) compared to diesel engines.

• Diesel engines are more fuel-efficient than petrol engines.

• Petrol engines are generally lighter and more compact than diesel e...read more

Types of brakes include disc brakes, drum brakes, regenerative brakes, and hydraulic brakes.

• Disc brakes use calipers to squeeze brake pads against a disc rotor.

• Drum brakes use brake shoes that press against the inside of a drum.

• Regenerative brakes convert kinetic energy into electrical energy to recharge the battery.

• Hydraulic brakes use fluid pressure to apply force to the brake pads or shoes.

Rectifier, types of motor, difference between servo motor and induction motor

• Rectifier is an electrical device that converts alternating current (AC) to direct current (DC)

• Types of motors include DC motors, AC motors, servo motors, and induction motors

• Servo motors are used in applications that require precise control of position, velocity, and acceleration

• Induction motors are commonly used in industrial applications du...read more

An encoder is a device used to convert motion or position into a coded signal.

• Encoders are commonly used in robotics, CNC machines, and industrial automation.

• They can be either absolute or incremental, with absolute encoders providing a unique code for each position and incremental encoders providing a relative change in position.

• Encoders can be rotary or linear, depending on the type of motion being measured.

• They are ...read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to either step up or step down voltage levels.

• Step down transformers decrease voltage levels, while step up transformers increase voltage levels.

• Types of transformers include power transformers, distribution transformers, isolation transformers, autotransformers, and...read more

PLC stands for Programmable Logic Controller. It is an industrial computer used to automate processes.

• PLCs are used to control and monitor industrial processes such as assembly lines, power plants, and water treatment facilities.

• They are programmed using ladder logic or other programming languages.

• PLCs can be used to control various types of equipment such as motors, valves, and sensors.

• They are designed to operate in ...read more

Handling pressure during work load requires effective time management, prioritization, delegation, and stress management techniques.

• Create a to-do list and prioritize tasks based on urgency and importance

• Delegate tasks to team members if possible

• Take breaks and practice stress management techniques such as deep breathing or meditation

• Communicate with colleagues and managers about workload and seek support if needed

• Main...read more

The least count of a vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the vernier scale and the main scale.

• It is usually 0.1 mm or 0.02 mm for a metric vernier caliper.

• For an imperial vernier caliper, the least count is typically 0.001 inch or 0.0001 inch.

• The least count is important for accurate measurements and should be considered w...read more

The symbol of third angle is ∠ and the symbol of first angle is ∠̂.

• The symbol ∠ is used to represent an angle in geometry.

• The symbol ∠̂ is used to represent an angle in engineering.

• The third angle projection method is commonly used in engineering drawings.

• The first angle projection method is commonly used in European countries.

• The symbol ∠ is also used in trigonometry to represent an angle.

5S is a workplace organization method that aims to improve efficiency and productivity by maintaining an orderly workplace.

• Sort - separate necessary items from unnecessary ones

• Set in order - arrange necessary items in a logical manner

• Shine - clean and inspect the workplace regularly

• Standardize - establish procedures and guidelines for maintaining the workplace

• Sustain - maintain the 5S system through continuous improvem...read more
