27 Fundamentals of Metalworking

Advances in metalworking have led to which of the following technical developments and processes in agricultural mechanics?

• Improved machinery and tools for farming

• Decreased crop yields

• Reduced need for any mechanical equipment

• Elimination of all manual labor in agriculture

The ferrous and nonferrous metals most commonly used in agricultural mechanics are:

• Steel and aluminum

• Copper and brass

• Lead and tin

• Zinc and bronze

A project plan for a metalworking project should include:

• Objectives, materials, timeline, and safety measures

• Only the list of materials

• A description of the final product only

• A list of tools without any timeline

Assorted tools are used for measuring and marking metal. Which of the following is commonly used for this purpose?

• Scriber

• Wood chisel

• Paint roller

• Pipe wrench

Select an appropriate cutting process for a specific project.

• Laser cutting

• Painting

• Welding

• Polishing

Various methods of shaping metals include:

• Casting, forging, rolling, and extrusion

• Welding, painting, soldering, and gluing

• Polishing, grinding, etching, and coating

• Cutting, drilling, sanding, and stapling

Threaded holes in metal parts are created by which process?

• Tapping

• Welding

• Casting

• Grinding

Metal parts can be fastened using which of the following methods?

• Welding, bolting, riveting, and soldering

• Painting, polishing, and sanding

• Melting, freezing, and evaporating

• Stretching, shrinking, and bending

The soldering process involves:

• joining two metals by melting a filler metal between them

• cutting metals using a sharp tool

• cooling metals rapidly to harden them

• painting metals to prevent rust

Various heat treatments affect metals in which of the following ways?

• They change the metal's hardness, strength, and ductility.

• They only change the color of the metal.

• They make metals always brittle regardless of type.

• They have no effect on the properties of metals.
