Electrostatic force is the reaction that holds together the electromagnetic field created by subatomic particles. It is stronger than gravity and occurs when two surfaces come into contact with each other. Coulomb’s law defines the fundamental theories concerning the electrostatic force of attraction. Electrostatic force is the phenomenon that derives from slow or stationary electric […]
Axial forces act on the central axis of an object, either stretching or compressing it. The geometric center is the point where the object’s mass is the same in any opposite direction. The central axis may or may not pass through the geometric center. When the force load is uniform across the geometric center, it […]
Constant force springs maintain a constant recoil force due to their unique design, unlike ordinary springs which follow Hooke’s law. They are used in self-retracting devices such as tape measures and seat belts to ensure consistent force in a small space. In most types of springs, the force exerted when that spring is compressed and […]
Force gauges measure mechanical power from push, pull or rotational force. They can be large machines used in manufacturing or small handheld devices. They measure forces applied through various methods and can measure everything from horsepower to muscle groups. Force dynamometer technology helps in many industries and is used for field tests for everything from […]
A force sensing resistor changes its resistance as pressure is applied, allowing for touch and weight sensing. It has applications in monitoring, automation, and robotics. It works similarly to the first resistive speed control units but is designed to handle less electrical energy. The resistor uses a polymer with conductive materials to decrease resistance as […]
Air Force firefighters are responsible for containing fires on military property, conducting search and rescue operations, and handling chemical and biological hazards. They also assist with repairing and strengthening installations and may administer basic first aid. A US Air Force firefighter contains fires on military property, primarily Air Force structures and runways. In addition, this […]
A force plate measures ground reaction forces exerted by a body and is used in biomechanical research and sports medicine. It allows for the collection of quantitative data on body movements, which can be useful in medical diagnoses and the development of new sports technologies. Force plates come in different sizes and types and can […]
To become an Air Force firefighter, one must first enlist in the Air Force and complete officer training procedures. This includes passing an entrance exam and physical and mental screenings. After completing basic training, one must apply to the fire protection program and obtain a degree in fire science. Other training programs may also be […]
Law enforcement officials receive guidelines and training on the use of force, but there are no universal standards. Most operate within a force continuum, deciding what level of force to use. The UN has adopted principles on the use of force, including the use of non-lethal weapons. Force is considered excessive if more than necessary […]
The Air Force Judge Advocate General’s Corps provides legal services to the US Air Force, including criminal defense and prosecution under the Uniform Code of Military Justice. JAG attorneys are often active duty members and attend law school at Air Force expense. The corps also employs paralegals and administrative support personnel and has a training […]
The Air Force has various requirements for enlistment, including age, education, physical and intellectual abilities, and residency status. Candidates must pass a professional examination and tests, meet visual acuity and health standards, and complete the Armed Services Vocational Aptitude Battery. After basic training, personnel must pass regular fitness tests and meet weight and waist size […]
The Air Force Judge Advocate General Corps, also known as JAG, provides legal services to members of the Air Force in areas such as criminal law, civil law, property law, and environmental law. JAG attorneys can serve as prosecutors, defense attorneys, or circuit defenders, and handle appeals in criminal cases up to the US Supreme […]
Central forces act only on the center of an object and the distance to another point. Gravitational and electrostatic forces are examples of central forces that can cause orbital motion. Hooke’s law can also produce a central force. Both inverse square law and Hooke’s law can produce closed orbital motion. A central force is a […]
Reasonable force is the appropriate amount of force to protect oneself, others, or property from harm, determined by a reasonable and objective observer. It can include lethal force and is used as a defense in court. It varies across jurisdictions and is a major concern for law enforcement. Police are trained to use minimal force […]
Excessive force is the inappropriate use of violence by law enforcement agencies, with no strict legal definition. Officers are expected to use common sense and reasonable force based on the level of resistance received. Emotional stresses can lead to violations, but strict regulations and media coverage have increased awareness and led to more restrictive rules […]
There are different paths to becoming an officer in the US Air Force, depending on your background and goals. These include ROTC programs, the Air Force Academy, and officer training school. Each path has unique requirements, including age and physical criteria. There are several roads you can take to become an officer in the United […]
Force majeure is a clause in contracts that justifies non-fulfillment of obligations due to uncontrollable circumstances, including natural disasters and man-made obstacles. The clause is not always sufficient justification and should be outlined completely to offer protection for both parties. Force majeure is a French term often used in contracts. The term means “majeure force” […]
An Air Force JAG provides legal advice to base officials and individual members of the Air Force. They work on a variety of legal issues and also serve as a personal advocate for any member who needs help. To become an Air Force JAG, one must complete law school and meet Air Force recruiting standards. […]
Force transducers convert forces into output signals that can be used by gauges, controllers, or data loggers. They can be hydraulic, pneumatic, or based on strain gauge sensors. Load cells are highly accurate and used in various industries. They have analog or digital outputs and can be connected to computers or data highways. Force transducers […]
Frictional force occurs when two surfaces make contact, resulting in resistance. There are two types: static and kinetic. Factors affecting friction include texture and pressure. Lubricants can reduce friction, but it can also generate heat and be dangerous. Friction can be helpful, such as in brakes and shoes. Frictional force refers to the result of […]
