Response to the following :
For a fixed, given load, the stress can be increased or decreased by changing the geometry of the system. Calculate the % change needed on the stress in Problem 1 to achieve a reliability of 99.5%.
Problem 1:
Consider a material with measured strength values F given in Table . Assume the expected stress values to be one-half of the values in Table. Calculate the safety factor and the reliability of the system.
