Ques:- Why the earth pin is thicker than other pins in a plug? Ifit is for reducing resistance, then why the copper earthwire is not so thick as earth pin of socket?
Right Answer: The earth pin is thicker than other pins in a plug to ensure a lower resistance connection and to handle fault currents safely. It also serves as a safety feature, ensuring that the earth connection is made before the live and neutral pins when plugging in. The copper earth wire is not as thick because it is designed to carry the expected fault current, which is typically lower than the current that the earth pin can handle during a fault condition.
Right Answer: Swagging is a metal forming process that involves deforming a workpiece by applying pressure to create a desired shape, often using a die. Fullering is a specific type of forging operation that involves reducing the cross-section of a metal piece by applying pressure with a tool called a fuller, which creates a groove or indentation.
Right Answer: A brief drive arrangement of a conveyor typically includes the following components:
1. **Drive Motor**: Provides the necessary power to move the conveyor.
2. **Gearbox**: Reduces the motor speed and increases torque to drive the conveyor belt.
3. **Drive Pulley**: Connected to the gearbox, it rotates to move the conveyor belt.
4. **Belt**: The surface that carries the material, looped around the drive and idler pulleys.
5. **Idler Pulleys**: Support the belt and maintain its tension and alignment.
This arrangement ensures efficient material handling along the conveyor system.
Right Answer: Reactor design involves selecting the type of reactor (batch, continuous, etc.), determining the reaction kinetics, and ensuring proper mixing and heat transfer. For plate and packed column design, it includes calculating the height and diameter based on mass transfer principles, selecting appropriate packing or tray types, and ensuring adequate flow rates for gas and liquid phases to achieve desired separation efficiency.
Ques:- A camel rests by a pile of 3000 bananas at the edge of a 1000-mile-wide desert. He plans to travel across the desert, transporting as many bananas as possible to the other side. He can carry up to 1000 bananas at any given time but he must eat one banana
Right Answer: QA (Quality Assurance) focuses on preventing defects by ensuring processes are followed and standards are met, while QC (Quality Control) involves identifying defects in the final product through testing and inspection.
Right Answer: Cutting clearance is the space or gap between the cutting tool and the workpiece that allows for the removal of material without causing damage to the tool or the part being machined.
Right Answer: Yes, Good Manufacturing Practices (GMP) help boost pharmaceutical export opportunities by ensuring product quality, safety, and compliance with international regulations, which builds trust with foreign markets.
Right Answer: Yes, GMP (Good Manufacturing Practices) is necessary even if there is a quality control laboratory, as it ensures that products are consistently produced and controlled according to quality standards throughout the manufacturing process.
Right Answer: Drill breakage can occur due to excessive feed rate, improper cutting speed, dull or damaged drill bits, inadequate cooling or lubrication, and incorrect drill alignment or setup.
