- There are different stress concentration factors for bending and torsional loads. - For flat end mills, it is recommended to use K t=2.14 for bending and K ts=2.62 for torsion. - These may be reduced by using key seats made with bull end mills. Key Points. Most commonly, a solution ‘s concentration is expressed in terms of mass percent, mole fraction, molarity, molality, and normality. When calculating dilution factors, it is important that the units of volume and concentration remain consistent.
