Problem 24.16 It has been observed that the yield strength of the material of a component is normally distributed wvith a mean of 230 N/mm? and a standard deviation of 30 N/mm2. The stress induced in the component is also normally distributed with a mean of 150 N/mm and a standand deviation of 15 N/nm. Determine the reliability used in designing the component.
