Abrasion resistance is the ability of a material to resist wear and damage caused by mechanical wear. It is useful in delicate applications such as building space shuttle components. Materials can be made abrasion-resistant through coatings or natural hardness. However, abrasion resistance does not make a material immune to wear and erosion. Abrasion-resistant materials can […]
Bearing resistance is the maximum weight a structure can hold before collapsing. It is used in engineering for building, aircraft, and transportation design. Calculations are necessary to avoid unnecessary stresses on load-bearing portions of the structure. Bearing resistance is a term used to describe the maximum amount of weight or pressure or some other variable […]
Muscular endurance exercises improve the ability to work under load for an extended period. Push-ups are a common home exercise, while circuit training is best for full-body workouts. Free weights can also be used, but stretching is important to avoid injury. Muscular endurance exercises are intended to promote a muscle’s ability to work under a […]
Resistance stretching starts muscles at their shortest point and uses the body’s own resistance to push them to their longest point, improving flexibility and strength. It is based on PNF stretching and can be done alone or with a trainer. It is believed to eliminate joint stress and correct bone alignment, and is popular among […]
Resistance wire is a durable alloy used as a heating element that can withstand electricity and heat. It comes in various lengths and must meet BS 115 requirements. Nichrome is a popular form of resistance wire used for cutting foam, working with polyurethane, and industrial heating. Temperature calculators are available to determine the appropriate resistance […]
Different types of resistance training equipment include free weights, weight machines, and resistance bands/tubes. Free weights require a large amount of equipment but provide high-intensity workouts, while resistance bands/tubes require less equipment but have limited resistance levels. Weight machines provide high levels of weight but require access to a large number of machines. There are […]
A resistance trainer is a type of cycling apparatus that attaches to the rear axle of a bicycle, providing resistance for indoor training. There are three types of resistance trainers: fluid, magnetic, and wind, each with varying levels of ride quality and adjustability. The term “resistance trainer” can refer to several types of fitness equipment, […]
Different types of resistance training equipment include free weights, weight machines, and resistance bands/tubes. Free weights require a large amount of equipment but provide a high-intensity workout, while resistance bands/tubes require less equipment but have limited resistance levels. Weight machines provide high levels of weight but require access to a large number of machines. There […]
Resistance equipment can build endurance, cardiovascular fitness, and muscle strength. Different equipment works on different parts of the body. Bikes, elliptical machines, and treadmills are great for cardiovascular endurance, while free weights and cable machines are good for muscular endurance. Plyometrics can be achieved with simple resistance equipment like medicine balls. Resistance equipment can refer […]
Electrical equipment must be connected to earth with low resistance. Regulatory agencies specify the maximum acceptable value for ground resistance, usually 5 ohms. Soil strength affects resistance, which is measured with an earth resistance meter using different methods including stakeless measurement. As a safety measure, all electrical equipment must be connected to a direct path […]
A resistor box contains multiple resistors connected to switches, providing instant access to a combination of resistances. It can be used for testing electrical properties and has a variety of designs and functions available for laboratory work. A resistor box is a typically compact piece of equipment that contains multiple resistors connected to one or […]
Resistance welding uses an easily melted material called a weld to join metal pieces. Heat is generated through an electric current, allowing for gentle welding of small components. Advantages include less risk of damage to components, faster production speeds, and increased safety. Drawbacks include higher initial costs and a more complex station. Welding and brazing […]
Malaria resistance refers to natural resistance in some human populations and drug resistance in Plasmodium parasites. Human resistance evolved in the ‘malaria belt’ due to changes in the natural environment, but can lead to deadly conditions. Resistance to antimalarial drugs is a global problem, requiring the development of new drugs that can target organisms tolerant […]
Speed endurance is the ability to run at maximum or near maximum speed for an extended period of time. Proper training, diet, and recovery are necessary for its development. Athletes tailor their workouts to their specific events and must focus on form and hydration. A high-carbohydrate and protein diet is recommended. Speed endurance is one’s […]
Endurance exercises like running, cycling, and swimming are recognized as resistance training, which improves cardiovascular and muscular endurance. Endurance athletes need both types of endurance to perform well, and strength training can also improve muscular endurance. Cross-training is important for overall fitness. Exercises that can be performed over a long period of time, such as […]
Resistance bands are elastic bands used for strength training exercises that are more convenient and portable than traditional weight lifting equipment. They come in various resistance levels and are an important part of an exercise program for building muscle mass and preventing falls, especially for older people. Resistance bands are used in strength training exercises. […]
Variable resistance weight lifting provides consistent resistance throughout the movement, resulting in a more intense workout and improved muscle strength. Specialized machines are required, but it provides a more comprehensive workout for stabilizer muscles. However, it is limited to one type of lift and requires multiple machines for a full-body workout. In fitness, variable resistance […]
Resistance exercise uses tension to build strength and size in skeletal muscles. It can be done with free weights, body weight, or resistance bands. Benefits include increased muscle mass, improved mobility, and reduced body fat. Consult a health professional before starting. Resistance exercise is usually made up of a strength training workout that uses some […]
Resistance movements are political protests against foreign occupation or government policies. They can be violent or nonviolent, such as the French underground resistance during WWII or Gandhi’s nonviolent resistance against British rule in India. Insurgencies and religious conflicts can also lead to resistance movements. Protests against a government can also be classified as resistance movements, […]
The French Resistance was a group of citizens who fought against the German occupation of France during World War II. They used guerrilla warfare, assassinations, and aiding the escape of Jews and others. The resistance grew and ultimately helped the Allied forces reconquer France. Members risked their lives and were often sent to concentration camps […]
