Conveyors are used in materials handling to efficiently transport goods or materials from one place to another.

• Conveyors help in automating the transportation process, increasing efficiency and reducing manual labor.

• They can handle a wide range of materials, from small parts to heavy items.

• Conveyors can be customized to fit specific needs, such as incline or decline conveyors for elevation changes.

• Examples of conveyors include belt conveyors, roller conveyors, and overhead co...read more

Types of pulleys commonly used in conveyors include drive pulleys, idler pulleys, and snub pulleys.

• Drive pulleys are used to transmit power from the motor to the conveyor belt.

• Idler pulleys are used to support and guide the conveyor belt.

• Snub pulleys are used to increase the angle of wrap around the drive pulley to improve traction.

• Other types of pulleys may include bend pulleys, take-up pulleys, and wing pulleys.

• Different pulleys may have varying diameters, materials, and co...read more

Various types of joints used in engineering include welded joints, bolted joints, riveted joints, and adhesive joints.

• Welded joints involve fusing two materials together using heat or pressure.

• Bolted joints use bolts and nuts to secure two materials together.

• Riveted joints involve using rivets to connect two materials.

• Adhesive joints use adhesives to bond materials together.

Preventive maintenance is the practice of regularly inspecting, servicing, and replacing parts to prevent equipment failure.

• Regularly scheduled inspections and maintenance tasks are performed to prevent breakdowns

• Replacement of worn out parts before they fail to avoid costly repairs

• Helps in increasing the lifespan of equipment and reducing downtime

• Examples include changing oil in a car engine, cleaning air filters in HVAC systems, and calibrating machinery

Belt length can be calculated using the formula: L = 2C + (πD)

• Measure the distance around the pulleys (C)

• Measure the diameter of the larger pulley (D)

• Use the formula L = 2C + (πD) to calculate the belt length

• For example, if C = 30 inches and D = 10 inches, then L = 2(30) + (3.14)(10) = 60 + 31.4 = 91.4 inches

TM stands for trademark, a symbol used to indicate that a particular product or service is legally protected.

• TM is used to protect logos, brand names, and slogans from being used by others without permission.

• It does not provide as much legal protection as a registered trademark (R), but still offers some level of protection.

• TM symbol can be used even before a trademark is officially registered.

• Example: Nike uses the TM symbol next to its logo to indicate that it is a protecte...read more

Coal is a fossil fuel formed from plant material that has been subjected to high pressure and heat over millions of years.

• Coal is primarily composed of carbon, along with small amounts of other elements like sulfur, hydrogen, oxygen, and nitrogen.

• There are different types of coal based on their carbon content and energy value, such as anthracite, bituminous, and lignite.

• Coal is used as a fuel for power generation, industrial processes, and heating.

• Coal mining can have environ...read more
