The Force Table is a great tool for teaching composition and addition of vectors, and it provides a platform for additional forces. It can be used to study the following: the concept of force, the direction of a force, the equilibrium of a material point, the intensity of different forces, the Rule of the Parallelograms, balancing forces, and more. It is easy to set up, and by varying the magnitude, forces, and pulleys, you can measure the resolving angles using the printed protractor located on the top of the table. Includes: • 1 Sturdy cast-iron base • 1 Force Table with protractor (30cm diameter) • 3 Pulleys attached to sturdy metal clamps • 3 Slotted weight sets (#250012) • 1 Spool of string
