Bar Breaking Apparatus

Product Code : SCL-POM-11849

Indian Lab Suppliers supplies the Bar Breaking Apparatus (Product ID: 11849) as part of its properties of matter range. It shows the large force a metal bar exerts when it contracts on cooling, by snapping a cast iron pin.

Quick Answer

A heavy cast iron frame with slotted end pillars carries a stout iron bar. One end of the bar is threaded for a large tensioning nut; the other has holes for the cast iron breaking bars. The iron bar is heated, the nut is tightened, and a breaking bar is inserted; as the bar cools and contracts it snaps the breaking bar. It is supplied with breaking bars, and spares are available. Use a burner away from flammables, let the hot bar cool untouched, and wear eye protection or use a screen because the breaking bar can fracture sharply.
