Demonstrate static equilibrium and vectors with PASCO's Statics System - a Magnetic Workboard and Components designed to teach the fundamentals of statics. The Statics System is composed of the Statics Board, Spares Package, Components package and Mass and Hanger Set.

The Statics Board is a ferrous metal plate (approximately 45 cm x 45 cm) and has a writable white board finish on both sides allowing for force diagrams, equations and notes to be written directly on its surface and easily erased.

Most of the components of the Statics System attach magnetically to the board and have rubber rings on their base to protect the board.

Perfect for demonstrations as well as group or individual explorations, the large array of investigations possible with Statics System makes it a flexible tool.  And it's compact size allows for easy storage.

## Typical Applications

• Hooke's Law
• Torque - Parallel Forces
• Center of Mass
• Torque - Non-Parallel Forces
• The Inclined Plane
• Simple Harmonic Motion
• Simple Machines
• Forces on a boom

## How It Works

The study of mechanics often begins with Newton's Laws of Motion. The first law describes the conditions for an object to maintain its state of motion. If the new force on an object is zero, the acceleration of the object is zero.

If ∑F = 0, then a = 0.

The second law describes what happens if the net force on an object is not zero. The acceleration is directly proportional to new force, in the same direction as the net force, and inversely proportional to mass, or

a = F net / m

Much of what is studied in an introductory course deals with the ways that forces interact with physical bodies. The PASCO Statics System is designed to help you investigate the nature of forces for the special case in which there is no acceleration. In other words, the vector sum of all the forces acting on the body is zero.

One reason to study the case of no acceleration is because it is easier to measure non-accelerating systems than it is to measure accelerating systems. A great deal can be leaned about the vector nature of forces by studying the many ways in which forces can be applied to an object without causing acceleration. The second reason is that in our everyday experience, non-accelerated systems are the rule, not the exception.
