quick overview :

Funicular Polygon and Forces Apparatus

Specification:

• Effective teaching
• Self-contained, bench mounted
• Direct measurement of forces
• Adjustable lines of action of forces
• Practical verification of triangle of forces, polygon of forces and link polygon
• Demonstrates equilibrium of forces at a point, applied to various points round a disc or acting on a rectangular lamina
• Concurrent & Non-concurrent coplanar forces

Experimental Capabilities:

• To resolve by experiment any suitable system of static coplanar forces which may or may not be concurrent
• To verify graphically using: a) triangle of forces for three concurrent coplanar forces b) polygon of forces for more than three concurrent coplanar forces c) link polygon for three or more non-concurrent coplanar forces
• To investigate (c) for either a disc or a rectangular shape
• To compare the accuracy of the experiment by comparing the experimental and graphical results
