Radial force is a force acting in a straight line perpendicular to the centerline of an object traveling in an orbital path, keeping it on a uniform orbit. It is important for designing tools and objects with rotating parts, such as bearings and power tool bits. Excessive radial force can lead to wear and failure. […]
The radial engine has cylinders arranged in a circle, making it lightweight and powerful for aircraft. It differs from the rotary engine and was used in WWII bombers, but was superseded by liquid-cooled designs in later years. Its design influenced modern Harley-Davidson V-twin motorcycle engines. The radial engine has its banks of cylinders arranged in […]
A radial arm saw is a versatile woodworking tool with a saw carriage that allows for vertical movement and bevel cuts. It’s ideal for home use, but not as easy to handle ripped lumber as a table saw. It accommodates different attachments and blades, and ranges in size from 8 to 12 inches. Prices range […]
Radial bearings support rotating axial loads by distributing forces along the radius. Deep groove bearings use balls or rollers to evenly distribute loads and can be self-aligning. Materials include steel and ceramic, with hybrid ceramic bearings offering higher speeds. Variations include split and caged designs, as well as self-aligning options with oval profiles. Radial bearing […]
The radial nerve supplies nerves to the forearm and the extensor compartment of the arm, including the triceps brachii muscle. Injury or dysfunction can cause pain, numbness, and difficulty extending the wrist or elbow. Treatment options vary depending on the cause and severity of the dysfunction. The radial nerve is a nerve found in the […]
A radial piston pump uses a drive shaft to move pistons in and out of cylinders to pump fluid. It differs from an axial piston pump in the arrangement of pistons and cylinders. The pump can be fixed or variable displacement and is used in various industries for its reliability and low noise. A radial […]
A radial drill press has an extended arm for drilling large workpieces. It allows movement in multiple directions and can drill non-vertical holes. Large industrial machines have large drill bits and cooling systems, while smaller DIY versions have similar flexibility. A radial drill press is a machine tool that has an extended arm or beam […]
Radial nerve damage can be caused by pressure, inflammation, or medical conditions. Symptoms include numbness, tingling, and difficulty moving the arm or wrist. Treatment includes medication, physical therapy, and surgery in severe cases. The radial nerve is found in the arm and helps control muscle movement and also allows the wrist to move backwards. This […]
Radial velocity is the motion of an object towards or away from a stationary observer, defined by both velocity and direction. Planets in circular orbits have little radial velocity relative to their suns, but to stationary observers outside the solar system, the planet changes its motion towards and away from them during its orbit. The […]
A radial head fracture is a common type of elbow fracture that occurs when the radial head, a bone in the forearm, breaks due to a fall. Treatment options vary depending on the severity of the fracture, and it can be difficult to identify on an X-ray. Seeking medical attention is important for a better […]
The pulse measurement is an easy way to count heartbeats and can be done by feeling the radial and carotid arteries. To take an accurate radial pulse, use only the first two fingers of the hand and count the beats for 10-15 seconds, then multiply by six or four to determine the heart rate count. […]
