SP4-0259
Overall size :350*350*355mm, Product Weight3.5kg Based on the principle that friction is easy to ignore in an earthquake, this 40 cm diameter table resolves angles to 0.5 degrees and uses glass quarter bends to display up to four-vector quantities at a time using washers to represent their relative magnitudes. Gentle tapping on the table lets the center ring migrate unless the vectors represented are truly in equilibrium
