The set includes four complete weight sets (each with brass slotted weights, 2 x 5g, 4 x 10g, 4 x 20g, and a 20g brass weight hanger), four pulleys with clamps and two sets of strings that allows students to investigate the equilibrium of either three or four forces. A 16" diameter lightweight, durable table top and sturdy cast iron support allow both ease of use and accuracy. Includes activity guide.
