The select of assurance coefficient is a problem that is often met in mechanical design. How to reasonably select it is a basic subject. The paper, from the view point of material strength, discreteness of stress and its statistics rule, suggests the calculating the reliability while calculating assurance coefficient in mechanical design, and gives a theoretical base for the scientifically selecting of assurance coefficient.q
