Torsion Testing Machine is a device used to measure the torsional strength and stiffness of a material. It is commonly used to test metals, plastics, and composites. The machine is designed to apply a twisting force to a test specimen and measure the resulting torque and angle of twist. The torsion testing machine consists of a drive motor, torque measurement system, load cell, and a test specimen holding fixture. The machine can be used for various applications, such as testing gears, shafts, and springs. Torsion Testing Machine is an important tool for quality control and research and development in industries such as automotive, aerospace, and manufacturing.
