A lathe is a machine tool used to shape and cut materials, typically metal, wood, or plastic, by rotating them against a cutting tool. As the material spins on the lathe, the cutting tool is applied to remove material and create smooth, precise shapes, such as cylindrical or conical surfaces. Lathes are commonly used in metalworking, woodworking, and manufacturing to create parts like shafts, screws, or furniture legs. They come in various sizes, from small benchtop models to large industrial machines, and are essential for tasks requiring high precision and detailed work.

A buttress is an architectural feature designed to provide support and stability to a wall or structure. Typically made of stone or brick, a buttress extends from the wall and often has a sloping design that helps distribute the weight and counteract the forces exerted on the structure, especially in tall buildings like cathedrals. Buttresses are commonly seen in Gothic architecture, where they are used to support the weight of high ceilings and large windows. There are different types of buttresses, including flying buttresses, which extend away from the building and are connected by an arch, allowing for more open space and larger windows. Buttresses not only serve a structural purpose but can also add an aesthetic element to the design of a building.

A viaduct is a type of bridge that consists of a series of spans or arches, typically used to carry a road or railway over a valley, river, or other obstacles. It is designed to maintain a high level of elevation and often features multiple supports, allowing it to traverse long distances. Viaducts are commonly made of concrete, stone, or steel and can be both functional and aesthetically pleasing, contributing to the overall landscape. They are essential in transportation networks, providing a reliable route for vehicles and trains while minimizing disruption to the natural terrain below.

An odometer is a device in a vehicle that measures the total distance the vehicle has traveled, typically in miles or kilometers. It works by using mechanical or electronic sensors connected to the vehicle's wheels to track the number of rotations. Each rotation represents a set distance, and the odometer keeps a running total. The reading is usually displayed on the dashboard and provides important information for maintenance, like when to change the oil or perform other service tasks. It is also used when buying or selling a vehicle to estimate its age and condition.

A torpedo is a small device placed on the track to signal an emergency or warn train operators about a problem ahead. These devices are typically used in situations where immediate action is needed, such as when a train needs to stop or slow down quickly due to an obstruction or accident. When a train runs over a torpedo, it makes a loud noise, alerting the crew to take action. Torpedoes were commonly used in the past, but modern technology has largely replaced them with electronic warning systems.

A console is a type of electronic device used to play video games. Unlike a personal computer, a console is designed specifically for gaming and typically connects to a television or monitor. Popular examples of gaming consoles include the PlayStation, Xbox, and Nintendo Switch. Consoles usually come with a controller for input and are often sold with pre-installed hardware and software that are optimized for gaming. They offer an easy-to-use and accessible way for players to enjoy games without needing to customize or upgrade hardware, as is often necessary with personal computers.
