Gephyrophobia is a fear of bridges, often caused by a traumatic event or fear of heights. Symptoms include panic, hyperventilation, and sweating. Avoidance is a common coping mechanism, but therapy and exposure therapy can help overcome the fear. Gephyrophobia is a phobia based on the fear of bridges. In general, most people with this phobia […]
Direct material inventory tracks materials available for production, including raw materials and supplies, to control costs and identify issues. Indirect materials are harder to track. Accurate records are necessary for accounting and insurance purposes, and computer programs can help with real-time updates. A direct material inventory is a detailed accounting of materials available for production […]
Mating pins are cylindrical connectors made of metal with parallel cross holes for keys to hold them in place. They evenly distribute sealing pressure and can be used as safety devices. Coupling pins can be disassembled easily and come in specialized varieties for stronger joints. Scaffoldings use steel coupling pins with tension clips for temporary […]
Mating pins are cylindrical connectors made of metal with cross holes for keys to hold them in place. They evenly distribute sealing pressure and can be used as safety devices. Couplings with drive pins can be easily disassembled and inspected. Specialized coupling pins strengthen joints, and steel coupling pins are used in scaffolding. A mating […]
A tower crane is a stationary device used to move large objects, often in construction or transportation. It has a fixed tower supporting a horizontal beam with cables to move objects. There are two types: standard and self-erecting. Tower cranes are rented or leased and require many safety precautions. In some cases, the crane tower […]
Creole sauce is a staple of Cajun cuisine, made with a tomato base, onions, celery, and peppers. It can be used as an ingredient in various dishes and is often served with rice and beans or as a topping on grilled meats and sandwiches. Creole sauce is a staple of Cajun cuisine and is used […]
Passive solar buildings use natural heat and light from the sun to reduce energy consumption. They are designed to maximize sun exposure for heating in cold climates and minimize it in warm climates. They may include features like solar water heaters and natural lighting. Passive solar design reduces energy costs and protects the environment. A […]
A phototransistor is an electronic component that amplifies and switches current based on exposure to light. It has exposed base sections that activate the component when exposed to light. The operating range can be controlled by the intensity of light applied. It is commonly used in devices such as optical remote controls, light pulse counters, […]
Propeller fans generate thrust using angled blades and are used for locomotion in airplanes and boats. The concept dates back to Archimedes, and was first proposed for propulsion in the 18th century. Propellers are based on Newton’s third law of motion and can have different numbers of blades. Incorrect specifications can result in a loss […]
Mixed rice dishes are popular worldwide, made with rice and other ingredients like meat, vegetables, or beans. Rice is a staple crop in many cultures, and mixed rice can be served as a main course, appetizer, or dessert. Different types of rice are used, each with their own nutritional value. Adding beans or peas can […]
Angular beams are directional sound waves used to test welds and metal components for defects. The equipment consists of a wedge and transducer, with different wedges pointing the beam at different angles. Transducers must be set at a specific frequency depending on the material being tested. Wedges can be curved for more accurate readings on […]
Platinum resistance thermometers (PRTs) are electronic devices used to evaluate changes in electrical resistance under extreme temperatures. PRTs are becoming the standard in resistive thermal devices due to platinum’s accuracy in sensing temperature in industrial processes. PRTs come in different forms, with film resistors being an alternative to carbon resistors. Platinum’s chemical inertness allows for […]
