FREE Mechanical Aptitude MCQ Question and Answers
What value stays the same throughout a ballistic trajectory?
Used largely in the same way as a brace, with the speed and flexibility of employing different accessories and bits being the difference.
A power drill is a versatile and widely used tool in various industries and DIY projects. It operates similarly to a traditional hand brace, which is a manual tool for drilling holes. However, a power drill offers the advantage of speed and convenience due to its electric motor, which allows for faster drilling and the ability to use different accessories and bits.
Which springs-related statement is FALSE?
Which one of the following DOES NOT operate via magnetism?
A vehicle does not operate via magnetism. Vehicles typically rely on mechanical systems such as engines powered by combustion or electricity to generate motion. While magnets and magnetism can be used in various aspects of vehicles, they are not the primary means of operation. For example, magnets can be used in electric motors or in some braking systems, but they are not the core mechanism that drives the vehicle forward.
Used in a power drill to create large holes in plastic or wood.
The tool used in a power drill to create large holes in plastic or wood is called a "Spade Bit," which is also commonly known as a "Flat Bit" or "Paddle Bit." Spade bits have a flat, wide, and paddle-shaped cutting head with a sharp point in the center. When attached to a power drill, they are efficient at quickly drilling large-diameter holes in soft materials like plastic, wood, or even some composites. These bits are commonly used in various woodworking and construction projects where larger holes are needed.
Used when dealing with bricks or concrete blocks to distribute, shape, and smooth mortar.
The tool used when dealing with bricks or concrete blocks to distribute, shape, and smooth mortar is called a Mason's Trowel, also known as a Brick Trowel. It is a flat-bladed tool with a pointed end, specifically designed for working with mortar during masonry and bricklaying tasks. Masons use the trowel to scoop up mortar from a mortarboard and apply it to the bricks or blocks, ensuring proper adhesion and alignment during construction.
What is the rate of rotation of the Earth's surface, expressed in kilometers per hour? The Earth has a 6370 km radius. Assign a whole number as the answer.
Which assertion concerning air pressure is TRUE?
Primarily used to cut fine joints in wood, as in a tenon, lap, or dovetail. It can also be used in conjunction with a miter box to cut accurate 45- or 90-degree angles.
The tool you are referring to is indeed a "Back Saw" or sometimes known as a "Tenon Saw." It is primarily used for cutting fine joints in wood, such as tenons, laps, or dovetails, thanks to its precise cutting ability.
Although the connection that sends current to the iron is chilly, an electric iron heats up. As a result of:
What distinguishes a cell from a capacitor most significantly?
Used when using a tap to cut internal screw threads. It makes it possible to apply pressure with a better and more even grip.
It is specifically designed to hold taps securely while cutting internal screw threads. Taps are used to create threads inside a hole, and the tap wrench provides a better and more even grip on the tap, allowing the user to apply the necessary pressure and control during the threading process. Tap wrenches come in various sizes to accommodate different tap sizes and are an essential tool for tasks involving threading and tapping operations.
An adjusting wrench for tightening or loosening nuts and bolts of various sizes.
A Crescent Wrench is a specific brand of adjustable wrench, but the more generic term for this type of tool is "Adjustable Wrench." It is designed to fit nuts and bolts of various sizes by allowing the user to adjust the jaw width using a worm gear mechanism. This flexibility makes it a versatile tool for tightening or loosening nuts and bolts in different applications.
A tool for plotting or drawing angles (0 to 180 degrees) on a surface.
The tool used for plotting or drawing angles on a surface, typically ranging from 0 to 180 degrees, is called a "Protractor." Protractors are commonly made of transparent plastic or metal and have a semicircular or circular shape. They usually have markings in degrees, allowing you to measure or draw angles accurately.
Used to establish the depths of grooves, mortises, and holes.
The tool used to establish the depths of grooves, mortises, and holes is called a "Depth Gauge." Depth gauges are precision instruments used in woodworking, metalworking, and other industries to measure the depth of cavities or holes.
Used in various related light electrical jobs as well as to solder wire to create contact terminals.
A soldering iron is a hand-held tool used in various electrical and electronics jobs, including soldering wire to create contact terminals. It consists of a heated metal tip that melts solder, a metal alloy used to join electrical components together. Soldering irons come in various wattages and tip sizes to accommodate different soldering tasks and components.
