• C+90+5

Breaking point of a wire is measured on a spring scale. In this apparatus, a wire is attached at one end to a spring scale, and at the other end to a cylinder that can be cranked. The tension in the wire is maintained by a ratchet wheel and pawl mechanism. The breaking point of the wire can be read in kilograms on the spring scale. MECHANICAL PROPERTIES OF MATERIALS
