Summarize the use of shears.
What will be an ideal response?
Shears work like powerful scissors. The correct placement of the metal being cut is as close to the pivot pin as possible. The metal being sheared must be securely held in place by the clamp on the shear before it is cut. If you are cutting a long piece of metal that is not being supported by the shear table, then portable supports must be used. As the metal is being cut it may suddenly move or bounce around; if you are holding on to it, this can cause a serious injury.
