Safety Chapter One Quiz

Actions that can distract workers, such as pushing, shouting, or practical joking. These behaviors can lead to serious accidents and create a negative work environment.

Always follow workplace regulations, even if they seem unnecessary. Rules are designed to protect workers and ensure safety.

Never remove safety guards from machinery. Guards are critical for preventing injuries during operation.

Always use appropriate lifting equipment for heavy objects. Never lift beyond your capabilities.

Electricity is invisible and powerful, and can be fatal if mishandled. Always treat electrical equipment with caution.

Compressed air can be helpful for tools and cleaning, but it can also be dangerous if misused. Never use compressed air for pranks.

Tools and scraps should be stored properly after use to prevent accidents and maintain a clean workspace.

Materials used in engineering applications, categorized into metals and non-metals.

Metals that contain iron, such as steel and cast iron.

Metals or combinations of metals that do not contain iron, including copper, aluminum, and alloys like brass.

Substances that are typically hard, brittle, and poor conductors of heat and electricity.

Metals that can be hammered or rolled into different shapes without breaking.

Metals that can be stretched into wires without breaking.

Mixtures of two or more metals, often with improved properties.

Materials that conduct heat and electricity easily.

Materials that resist the flow of heat and electricity.

A metal that allows the easy flow of electricity through it.

A soft, ductile metal with high corrosion resistance. Used in electrical cable sheaths, solder alloys, and accumulator plates.

The most conductive metal, known for its softness and low tensile strength. Widely used in electrical and electronic engineering.

A metal that resists corrosion and is used to coat steel for protection. Also found in soft solders and bronzes.

A soft, ductile metal that is corrosion resistant. Used in galvanized iron and die-casting alloys.

A device that transfers heat from one medium to another.

An alloy primarily composed of copper and tin, known for its strength and corrosion resistance.

An alloy primarily composed of copper and zinc, known for its malleability and durability.

The ability of a material to resist being pulled apart.

The smallest difference a measuring instrument can detect.

The ability of a measuring device to display the measured values.

The closeness of repeated measurements to each other.

The closeness of a measurement to the true value.

The allowable variation in a dimension or component.

The intended size of an object, before considering tolerance.

The difference between the maximum and minimum allowable values within the tolerance.

A measuring tool used for accurately transferring distances.

The error that occurs when a measurement is taken from an angle, instead of directly from the measurement point.

A type of sand mold that uses clay as a binder, offering versatility in creating complex part geometry, but has limitations in dimensional accuracy, surface finish, and porosity.

A sand mold utilizing organic binders instead of clay. It requires a backing material for support.

A sand mold where the surface is hardened to a specific depth using heat, and special bonding materials are added for strength.

A two-part container (cope and drag) used to hold and mold sand around a pattern.

A model used to create the mold cavity, meticulously crafted to account for metal shrinkage and other necessary adjustments during the casting process.
