Description

• • Bar breaking apparatus designed to demonstrate thermal expansion and contraction of metals.
  • To demonstrate the forces involved in thermal expansion or contraction. Consists of a heavy cast iron frame with slotted end pillars that support an iron bar.
  • The bar is threaded at one end, allowing for the attachment of a large tensioning nut, and it features holes at the other end to accommodate the cast iron breaking bars.
  • Bar measures 13″ long.
  • Great for physics classrooms.
  • Heating source and Bunsen burner not included.
