1J30.50 Vertical Force Table

A force table in the vertical plane – when the forces from the different strings are balanced, the ring does not touch the pin at the center of the table, demonstrating the system is at rest. Angles are drawn on the table to allow the demonstrator to calculate forces in the horizontal and vertical directions, if desired.

A classic circular force table is vertically oriented in this photo. The force table is face-on. Four strings are attached to a central ring that hovers at the center of the force table. Each of the four strings is drawn over a pulley held on an angled, movable arm. The pulleys are set at the ends of these arms, well beyond the outer rim of the force table. A mass hanger hangs from each of four pulleys. The pulleys are set at angles around the force table: 30 degrees, 120 degrees, 210 degrees, 280 degrees.
