About This Product
Thread is the link in many mechanics practicals: it carries tension over a pulley, joins the central ring of a force table to its weight hangers, and holds the bob of a simple pendulum. Frayed or damaged thread should not be used for heavier loads, and knots should be checked before weights are hung. Laboratories and colleges in Bosnia and Herzegovina, Belize, South Sudan, Madagascar and Kiribati can buy the Spool of thread through an export order.
