    New Ways To Measure Torque May Make Your Current

    Really, torque is an important factor in anything that rotates or spins on a shaft, spindle or axle. A lumber mill might use a predetermined maximum torque to initiate blade changes. This saves wear on the drive system and increase product quality. This may seem like a bit of an overstatement. But if you need to measure torque and you have not
