FREE Mechanical Aptitude Tools Question and Answers
Used to measure the amount of electrical current flow (calibrated in amperes).
An ammeter is a device used to measure the amount of electrical current flowing through a circuit. It is calibrated in amperes, which is the unit of measurement for electric current. Ammeters are essential tools in electrical engineering, electronics, and various fields where precise current measurements are necessary.
Used to add more torque when driving screws or manually drilling holes in wood. Several bits are compatible with this tool.
A brace is a hand tool used for adding more torque when driving screws or manually drilling holes in wood. It is an old but still effective tool for woodworking tasks that require precision and control. Braces have a U-shaped frame with a handle at one end and a chuck at the other end where different bits can be attached.
Used to smooth out rough edges on metal work pieces or to sharpen equipment. Additional cleaning and polishing of metal work can be done with a wire brush or buffer wheel.
A bench grinder is a stationary power tool that is mounted on a workbench or pedestal. It consists of two grinding wheels, typically made of abrasive material, that rotate at high speeds. The grinding wheels are used for smoothing out rough edges on metal workpieces and for sharpening various tools and equipment.
Used to drill holes in wood, metal, or plastic using a power drill.
Twist drill bits are the most common and widely used type of drill bits. They have a helical flute design, which gives them the name "twist." The flutes on the drill bit allow the chips or shavings created during drilling to be removed from the hole.
A concrete, marble, etc. cutting blade for a portable circular saw.
Employed to indicate or check angles on a work component. A protractor is typically used as a frame of reference.
A T-Bevel is a measuring tool used to indicate or check angles on a work component. It consists of a handle and a metal blade that can be adjusted to any angle and locked in place. The T-Bevel is often used in conjunction with a protractor, which serves as the frame of reference to measure or transfer angles accurately.
A blade for a portable circular saw that can cut grooves and/or ridges in corrugated sheet metal.
A cutting device for chopping or hewing timber and felled trees.
A felling axe is a specialized type of axe designed for felling (cutting down) trees and chopping timber. It typically has a long handle, known as the haft, and a large, sharp axe head. The axe head is shaped and weighted in a way that allows it to efficiently cut through wood fibers and facilitate the felling process.
Used to cut metal or thought steel using a flame produced by a mixture of oxygen and acetylene.
A cutting torch is a handheld tool commonly used in metalworking and welding applications. It operates by combining oxygen and acetylene gases in a controlled manner to produce a high-temperature flame known as an oxy-acetylene flame. This flame has the capability to melt and cut through various types of metals.
Used to drive screws with a Phillips head. Compared to grip obtained with traditional slotted- or flared-tip screwdrivers, its design improves grip.
An adjustable wrench used too grip round objects like metal pipes or steel rods.
A Pipe Wrench is an adjustable wrench specifically designed to grip round objects like metal pipes or steel rods. It is one of the essential tools used by plumbers, pipefitters, and other tradespeople working with pipes.
Used to determine a true horizontal line or accurate level of a surface.
A level is a basic hand tool commonly used in construction, carpentry, and various DIY projects to ensure that surfaces are flat and properly aligned. It consists of a straight, rigid body with a bubble or spirit level vial mounted on it. Inside the vial, there is a liquid (usually a colored spirit or oil) and an air bubble.
A manual tool for sharpening tools that is a rectangular stone made of coarse abrasive.
Whetstones, also known as sharpening stones or water stones, are used for honing and sharpening the edges of blades, knives, chisels, and other cutting tools. They come in various sizes and grits, ranging from coarse to fine.
Used to file flat surfaces; suitable for usage with most materials.
Flat files are hand tools designed for smoothing and shaping surfaces. They consist of a hardened steel bar with a flat profile, and one or both sides of the file have rows of parallel teeth or cutting edges. These teeth are what allow the file to remove material and create a smooth finish on the workpiece.
Used as a tool to penetrate the surface of a wooden work piece with nails.
A nail punch is a small hand tool used in woodworking and carpentry to drive nails below the surface of the wood. It is used after the nail has been partially driven into the wood using a hammer. The nail punch is then placed on top of the nail head, and a few taps with the hammer drive the nail below the wood's surface.
Used to grasp and rotate pipes without scratching the external coating.
A strap wrench is a versatile hand tool designed to provide a secure grip on smooth cylindrical objects, such as pipes, tubes, and fittings, without damaging their surface. It consists of a flexible strap made of strong material (usually nylon or rubber) and a handle. The strap wraps around the object to be turned, and as the handle is turned, the strap tightens around the object, providing a firm grip.
