Laboratory Tongs

Demonstrates the typical concept behind the architecture of roman arch structures, which are famous for their strength in compressive loading. Comprises a pre assembled 3-part buttress and a set of 23 wooden blocks. Fully assembled arch can easily support the weight of a child.

With effective scale lengths of nearly 9″, Rotary scales offer greater accuracy than linear scales. All balances are graduated in gram/Newton. Dial: 3″ diameter metal suspension ring at top and hook at bottom.
