ANSWER-
A radial arm saw is a type of power saw that is commonly used for cutting lumber, sheet materials, and other large pieces of wood. It is named after the radial arm that extends out from the saw's motor and supports the cutting blade. The radial arm saw is designed so that the blade can be adjusted in height, angle, and bevel, making it a versatile tool for a variety of cutting tasks. The saw is usually mounted on a sturdy base, and the blade can be extended out to reach the material being cut, making it easier to make precise cuts without having to move the material. Radial arm saws are often used in woodworking shops and in home workshops, and they can be found in both professional-grade and consumer-grade models.
