Description
The Precision Force Table is an excellent tool to teach vectors, with components for investigating the equilibrium of either 3 or 4 forces. The 16″-diameter lightweight tabletop displays a dual scale marked in 1/2° increments; the outer scale has an accurate pulley positioning system and the inner scale accommodates overlays for tracing paper. The pulley clamps have line markings for highly precise measurements; the sturdy cast iron support has leveling screws. The table is quickly assembled and disassembled and stores easily.
Table comes with an activity guide, 4 weight sets (each with slotted weights, 2 x 5 g, 4 x 10 g, 4 x 20 g, and a 20 g weight hanger), 4 pulleys with clamps, and 2 sets of strings, giving students the option to investigate equilibrium for either 3 or 4 forces.
