dc.description.abstractThe fatigue testing machine that uses the force of torsion is invented to be a compact machine that uses the torsion as the force in the test. From the tests, it achieved the highest of 200 newton meters using pneumatics to test the metal materials, i.e. the steel S45C molded in accordance with the JIS Z 2274 standard. To find out the capacity of the fatigue testing machine that uses the force of torsion with 8 mm, 10 mm, and 12 mm diameter test pieces, the machine was tested with different levels of the force of torsion and the percentage of the deviation of the tests did not exceed the limit of + 10 percent. This research could reduce the cost of the procurement of the fatigue testing machine that uses the force of torsion and could be used in the instruction in the department of mechanical engineering, faculty of engineering, Rajamangala University of Technology Phra Nakhon in the future.en_US
