Product Information

Simple concept and robust construction guarantee reliable lab success. A hanging mass and a counter-balance are attached to a horizontal bar mounted atop a vertical shaft about 45cm high, and the suspended mass is tied to the vertical shaft with a horizontal spring. When the shaft is spun, the suspended mass swings away. The displacement at any given speed is marked by a vertical mounted pointer that can be moved laterally to match the pointed tip of the suspended mass. From the mass, the speed of rotation and the radius, one can quickly calculate the centripetal force.

Using the included weight hanger and ball-bearing pulley, you can measure the force required under static conditions to displace the mass the same distance against the pull of the spring. Spring and mass are dimensioned to ensure a rotational speed slow enough to be safe and easily counted. The vertical shaft rests in a ball-bearing mount that minimizes wobble and friction. The entire device is mounted on a 15 x 41cm base with three adjustable feet.
