What tool is used for measuring small external dimensions with high accuracy?
A Depth gauge
B Ruler
C Vernier caliper
D Micrometer
A micrometer is used to measure small external dimensions with high precision, typically for parts with thickness or diameter within a small range. Unlike Vernier calipers, which measure larger dimensions, micrometers provide more accuracy for small measurements.
What is the main purpose of a file in workshop practice?
A Shaping material
B Measuring dimensions
C Polishing surfaces
D Cutting material
A file is primarily used to shape and smooth materials, typically metals or plastics. It removes small amounts of material to refine the surface finish or shape. It is not used for cutting or measuring like other tools.
What is the function of a drill press?
A Cutting threads
B Drilling holes
C Shaping material
D Grinding surfaces
A drill press is a machine used to drill precise holes in materials. It provides more control and accuracy compared to a handheld drill, especially for repetitive operations. It does not perform cutting, threading, or grinding.
Which measurement tool is commonly used to measure internal dimensions?
A Micrometer
B Depth gauge
C Inside caliper
D Vernier caliper
Inside calipers are specifically designed for measuring the internal dimensions of a hole or cavity, such as the internal diameter. They work by expanding inside the part and can be measured with a micrometer or Vernier caliper.
What does a sheet metal work process typically involve?
A Cutting and shaping metal
B Welding metal parts
C Drilling holes in metal
D Measuring metal dimensions
Sheet metal work involves cutting, bending, and shaping thin sheets of metal into required forms. This includes processes like shearing, punching, and folding. It is commonly used for making parts like enclosures and brackets.
What is the purpose of a hand saw?
A Shaping edges
B Grinding surfaces
C Measuring
D Cutting material
A hand saw is used to manually cut materials, typically wood or metal. It has a serrated blade that allows for effective cutting. Unlike tools used for grinding or shaping, a saw is primarily designed for cutting through solid materials.
Which tool is used to measure large external dimensions with moderate precision?
A Vernier caliper
B Micrometer
C Steel tape measure
D Ruler
A steel tape measure is commonly used for measuring large external dimensions. It is less precise than micrometers or Vernier calipers but provides an effective and flexible tool for measuring longer lengths or dimensions of large parts.
What type of joint is typically used in sheet metal work?
A Butt joint
B Rivet joint
C Threaded joint
D Welded joint
Rivet joints are commonly used in sheet metal work. This involves using rivets to join metal pieces together. Riveting is a popular method for creating strong, permanent connections in sheet metal fabrication, especially in aerospace and construction industries.
What tool is commonly used to remove small amounts of material for precise finishing?
A Drill
B Saw
C File
D Chisel
A file is used to remove small amounts of material for precise finishing of workpieces. It is commonly used to smooth or shape metal, wood, or plastic surfaces. Unlike saws and drills, files are designed for fine finishing and detailing.
What type of saw is used for cutting curves in wood or metal?
A Hand saw
B Circular saw
C Hacksaw
D Jigsaw
A jigsaw is a type of saw used for cutting curves and irregular shapes in wood, metal, or plastic. It uses a straight, fine-toothed blade that moves up and down to make intricate cuts, unlike other saws that are better suited for straight cuts.
What is the purpose of a tap in workshop practice?
A Cutting threads
B Smoothing surfaces
C Drilling holes
D Measuring dimensions
A tap is a tool used for cutting internal threads inside a hole. It is essential for creating threaded holes where bolts, screws, or other fasteners can be inserted. Tapping creates a consistent and accurate thread pattern for fastening.
What is a common feature of a milling machine?
A Fixed cutting tool
B Cooling mechanism
C Rotating cutting tool
D Threading tool
A milling machine typically uses a rotating cutting tool to remove material from a workpiece. It can create a variety of shapes and surfaces, including flat, curved, or irregular forms. Unlike turning machines, it does not rotate the workpiece.
What does a beveling tool do?
A Joins metal parts
B Creates angled edges
C Measures dimensions
D Cuts straight edges
A beveling tool is used to create angled edges on a workpiece, typically in metal or wood. It is commonly used to prepare edges for welding or joining, providing a smooth and precise angle to ensure proper fitment of parts.
What is a common application of a Vernier caliper?
A Cutting materials
B Bending metal
C Measuring small external dimensions
D Measuring large dimensions
A Vernier caliper is used to measure small external dimensions with high precision, such as the diameter or thickness of parts. It can also measure internal dimensions and depths but is most often used for external measurements in mechanical work.
What is the primary purpose of a surface plate in a workshop?
A Supporting workpieces
B Holding tools
C Shaping metal
D Cutting material
A surface plate is a flat, stable surface used to support workpieces during measuring or machining processes. It provides a level reference surface to ensure accurate measurements and helps with alignment during various operations like layout and marking.
