Green strength is the ability of a product to withstand handling and processing before it is fully cured. It is important in high throughput processes like injection molding and powder metallurgy. A high green strength is desirable to prevent damage to the finished product. The ceramics, thermoplastics, and metal powder molding industries benefit from good […]
In 1943, Franklin D. Roosevelt flew a Boeing 314 Dixie Clipper to the Casablanca Conference, becoming the first US president to travel by air while in office. The first official presidential aircraft was a reconfigured Douglas C-54 Skymaster called the Sacred Cow, which had an elevator for Roosevelt’s wheelchair. Other presidents, including Harry Truman and […]
The Air Force training program teaches recruits job-specific skills and is taught by military instructors. The length of training varies by job, and recruits must pass a test to complete the program. Physical training is less severe, and upon completion, recruits are ordered to their duty station. The training may also help with civilian employment. […]
Air Force retirement eligibility requires a minimum of 20 years of service, but rules may change for those in the National Guard or Reserve. Rank and age restrictions also apply, and behavior can affect retirement. Consultation with the Military Personnel Flight is recommended. Air Force retirement requirements may vary depending on the service of the […]
Lackland Air Force Base in Texas hosts a six-week basic military training program for recruits. The program teaches Air Force history, military lifestyle, physical fitness, and teamwork. The training is divided into sections that change each week, focusing on paperwork, clothing, haircuts, rank insignia, marching, military lifestyle, physical training, and discipline. The ultimate goal is […]
The Air Force Reserve offers jobs in engineering, logistics, medicine, and aircraft maintenance. Traditional reservists work part-time, while civil engineers work on air bases and maintenance workers inspect and repair aircraft. Logistics personnel arrange transportation and supply chains, and health professionals work in treatment facilities. There are several types of Air Force Reserve jobs in […]
Force gauges measure muscle strength using compression, push, or pull devices with analog or digital meters. They can measure strength in various areas of the body and can be used for medical, sports, or fitness therapy applications. Accessories like detachable grips can extend their capabilities. They can be analog or digital and vary in quality […]
Absolute force is the maximum amount of force a muscle can exert under involuntary stimulus, but the body has receptors to prevent harm. Bodybuilders train to achieve maximum strength, but the body only uses absolute force in emergency situations. Maximum strength can be increased with training, but the body always has a reserve of strength. […]
The Air Force Tuition Assistance Benefit pays for 100% of tuition up to $4,500 per year for Air Force Reserves and active members. Restrictions apply, including having a degree plan and taking classes that will help earn a higher degree. Assistance is also available for members of other branches and veterans. Assistance in Air Force […]
The Internet Engineering Task Force (IETF) is a group of volunteers who develop and publicize Internet standards through specialist teams and working groups. They lack formal authority but have created many widely used protocols, including HTTP and IPv6. The IETF collaborates with other groups and receives support from the Internet Society. Standards are approved by […]
Strength resistance training involves maintaining maximum strength level for as long as possible. It is useful in sports where athletes need to use maximum physical effort repeatedly for a long time. Balancing rest periods is key to building strength endurance. Resistance to force is a measure of the body’s ability to continuously perform repetitive acts […]
A brute force attack is a trial and error method used to crack passcodes or keys. It can take a long time to find the correct combination, but success depends on the length and complexity of the passcode. To prevent attacks, it’s best to use complicated passwords and avoid easily guessable words. Many accounts also […]
The Air Force ROTC Scholarship pays for tuition, books, room, and board for students in American colleges and universities who participate in the ROTC. Scholarships are offered for 2-4 years and cover any discipline deemed necessary by Air Force requirements. The program has scholarships for high school students, college students, and Air Force personnel. Upon […]
Air Force optometrists perform routine eye exams and treat eye health conditions for service personnel and their families. They must have an OD degree and be licensed to practice in the US or its territories. The Air Force provides equipment, supplies, and support personnel. An optometrist is a licensed professional who has completed a minimum […]
Surface force, or surface tension, is the upward force that the surface of a liquid exerts on an object. It allows small insects to walk on water and makes water sports possible. Surface force occurs because of the molecules at the surface of a liquid. Adding soap or increasing temperature can decrease surface strength. Surface […]
The normal force keeps solid objects apart due to the electromagnetic forces of atoms repelling each other. It is perpendicular to the surface causing it and is important in calculating friction between solid objects. It cancels out the gravitational force on level ground but not on a hill. When two objects collide, momentum is responsible […]
The term “applied force” refers to a contact force between a person and an object. It is difficult to calculate and often found in conjunction with other forces. The equation of the applied force depends on the situation, but can be calculated using F=MxA. Opposing forces such as friction, gravity, or air resistance must be […]
Centrifugal force is the outward pressure around an object as it rotates. It can be explained by Newton’s law of inertia, but not all aspects are understood. It is used in everyday life, such as in clothes dryers and medical centrifuges. Understanding is not necessary to benefit from it. Centrifugal force is the force describing […]
Mains pipes are pressurized pipes used to carry water, wastewater, and other materials. They can be gravity-fed or forced, depending on the terrain. Engineers determine the need for pressure and calculate the best size and pressure to avoid public health risks. A mains pipe is a pressurized main pipe that can carry water, wastewater and […]
The electromagnetic force is one of the four fundamental forces of nature, responsible for electricity, magnetism, and light. It operates over unlimited distances and follows the inverse square law. Objects with different charges attract each other, while those with the same type repel each other. The force is mediated by “virtual” photons, and the theory […]
