This tool is said to shear the bar,and the resistance which the bar opposes to this stress iacalled its strength to resist shearing. The tools practicallyused to shear are not quite square at the edge, and [strength of MATRBTiTt^ therefore cut slightly, but for true shearing the lower faceought to be square, and the tool should come down clost.
