What is the main purpose of assembling in workshop practice?
A Cutting material
B Shaping material
C Joining parts
D Measuring parts
Assembling refers to the process of putting together various parts or components to create a complete product or system. It is crucial in manufacturing and repair to ensure the functionality and integrity of the final product.
What is the purpose of lubrication in maintenance?
A To prevent wear and tear
B To cool the material
C To measure dimensions
D To bond materials
Lubrication is used to reduce friction between moving parts, thereby preventing wear and tear, reducing heat, and ensuring smooth operation. It is essential in maintaining machines and tools for optimal performance and longevity.
What does soldering primarily involve?
A Polishing surfaces
B Shaping materials
C Cutting materials
D Joining metals with heat
Soldering is a process that uses heat to melt a filler material, typically a low melting alloy, to join metal parts together. It is commonly used in electrical work and plumbing for creating durable connections.
What is a common tool used in assembling parts in mechanical work?
A Saw
B Screwdriver
C Hammer
D Chisel
A screwdriver is commonly used in assembling parts to insert and tighten screws. It helps hold components together by fastening them securely. Hammers, saws, and chisels are used for other tasks like shaping or cutting.
What is the role of maintenance in workshop practice?
A Enhancing precision
B Joining parts
C Keeping tools in working condition
D Shaping materials
Maintenance involves regular checks, cleaning, and repairing of tools and machines to keep them in optimal working condition. It ensures longevity, reliability, and safety of equipment, preventing unexpected failures during operations.
Which process is typically used for joining electrical components?
A Soldering
B Grinding
C Bending
D Welding
Soldering is the preferred method for joining electrical components because it uses a low temperature filler metal to bond wires, connectors, and other electrical components without damaging sensitive parts, ensuring electrical conductivity.
What type of maintenance focuses on preventing breakdowns before they happen?
A Reactive maintenance
B Corrective maintenance
C Predictive maintenance
D Preventive maintenance
Preventive maintenance is scheduled maintenance performed to prevent machinery failures before they happen. It includes routine checks, lubrication, and part replacements, which help extend the lifespan of equipment and minimize downtime.
What is the common method for sealing metal joints in piping systems?
A Gluing
B Welding
C Threading
D Soldering
Soldering is commonly used in piping systems to seal metal joints, especially in plumbing and electrical work. It creates a reliable, leak proof bond by melting a filler metal, which solidifies to form a joint.
What is the primary purpose of a torque wrench?
A Measuring dimensions
B Cutting material
C Tightening bolts to specific tension
D Shaping materials
A torque wrench is used to tighten bolts or nuts to a specific torque value, ensuring that they are neither too loose nor too tight. This is crucial in applications where proper tension is essential for safety or performance.
What is a key benefit of using hydraulic systems in workshop machinery?
A Provides high force with less effort
B Reduces wear
C Prevents material waste
D Increases cutting speed
Hydraulic systems use fluid pressure to generate large amounts of force with minimal effort. This makes them ideal for tasks requiring high power, such as lifting, bending, and pressing materials, with great precision and efficiency.
What tool is used for cutting through thick metal materials?
A Jigsaw
B Hacksaw
C Chisel
D Plasma cutter
A plasma cutter uses a high velocity jet of ionized gas to cut through thick metal materials quickly and precisely. It is used in fabrication and repair work for cutting metal sheets, pipes, and plates.
What is the role of the assembler in mechanical engineering?
A Manufacture tools
B Maintain machinery
C Put together parts to form products
D Design products
An assembler is responsible for physically putting together components to form a product. This includes aligning, fastening, and sometimes testing the assembly to ensure it meets design specifications and operates correctly.
What type of maintenance involves fixing equipment after it breaks down?
A Predictive maintenance
B Corrective maintenance
C Preventive maintenance
D Proactive maintenance
Corrective maintenance involves fixing equipment after a breakdown occurs. It aims to restore the functionality of equipment that has failed and is typically less cost effective than preventive maintenance, as it often results in unplanned downtime.
Which tool is commonly used in carpentry to shape wood?
A Plane
B Chisel
C Hammer
D Lathe
A plane is a carpentry tool used to smooth or flatten the surface of wood. It removes thin layers of material to create a smooth finish or achieve a specific thickness, commonly used in fine woodworking.
What is the primary purpose of a pipe wrench in workshop practice?
A Bending pipes
B Cutting pipes
C Holding pipes
D Tightening bolts
A pipe wrench is designed to grip and hold pipes securely during plumbing or pipefitting tasks. It is especially useful for tightening or loosening pipes, ensuring proper fittings during assembly or maintenance of plumbing systems.
