1st angle projection is a method of creating a 2D drawing of a 3D object where the view is projected onto a plane located in front of the object.

• The object is placed in the first quadrant of the coordinate system

• The plane of projection is placed between the object and the observer

• The observer looks towards the object through the plane of projection

• The view of the object is projected onto the plane of projection

• Commonly

3rd angle projection is a method of creating a 2D drawing of a 3D object where the view is projected onto a plane from the opposite side of the object.

• The object is placed in the third quadrant of the coordinate system.

• The view is projected onto a plane that is placed in front of the object.

• The resulting drawing shows the object as if it has been sliced and unfolded onto the plane.

• Commonly used in engineering and manuf...read more

GD&T stands for Geometric Dimensioning and Tolerancing, a system used to define and communicate engineering tolerances.

• GD&T is a language used to communicate design intent and ensure parts are manufactured to the correct specifications.

• It uses symbols and annotations to define the allowable variation in form, orientation, location, and size of features on a part.

• GD&T is important for ensuring parts fit together correct...read more

A crossed cheque indicates that the amount should be deposited into the payee's account and cannot be cashed over the counter.

• Crossed cheques have two parallel lines on the top left corner.

• The payee's name is written on the cheque, and only they can deposit it into their account.

• Crossed cheques are more secure than open cheques as they prevent fraud and theft.

• Banks may charge a fee for processing crossed cheques.

Priming is the process of filling the pump and suction pipe with liquid to remove air and create a vacuum.

• Priming is necessary to ensure the pump can function properly.

• It involves filling the pump and suction pipe with liquid to remove air and create a vacuum.

• This helps to prevent cavitation and damage to the pump.

• Priming can be done manually or automatically depending on the type of pump.

• Examples of pumps that require...read more

Transformer losses refer to the energy losses that occur during the operation of a transformer.

• Transformer losses include copper losses and iron losses.

• Copper losses occur due to the resistance of the transformer windings.

• Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.

• Copper losses can be minimized by using larger conductor sizes and reducing the resistance of ...read more

Efficiency of transformer is the ratio of output power to input power.

• Efficiency is affected by factors such as core losses, winding resistance, and load impedance.

• Efficiency can be improved by using high-quality materials, proper design, and regular maintenance.

• Efficiency is expressed as a percentage and can range from 50% to 99% depending on the transformer type and application.

Non-sparking equipment and lights are used in hazardous environments to prevent explosions.

• Non-sparking tools are made of materials that do not create sparks when struck or rubbed against each other.

• Non-sparking lights use LED technology and are enclosed in a housing that prevents sparks from escaping.

• These techniques are commonly used in industries such as oil and gas, chemical, and mining.

• Examples of non-sparking too...read more

Baud rate is the rate at which data is transmitted over a communication channel.

• Baud rate is measured in bits per second (bps).

• Higher baud rates allow for faster data transmission.

• Baud rate must be set the same on both ends of the communication channel.

• Incorrect baud rate settings can result in data corruption or loss.

• Examples of communication channels that use baud rate include UART, SPI, and I2C.

I2C is a serial communication protocol used to connect multiple devices with two wires. Pull-up resistors are necessary for proper communication.

• I2C uses a master-slave architecture where the master initiates communication.

• Each device on the bus has a unique address assigned to it.

• Data is transmitted in packets with a start and stop bit.

• Pull-up resistors are necessary to ensure proper voltage levels on the bus.

• The valu...read more
