An assembly composed of three parts has a total nominal leng

An assembly, composed of three parts, has a total nominal length of 1.500 inches with a tolerance of +/-0.050 inch. The three parts are essentially identical in terms of the processes manufacturing each. The processes making the parts (and the assembly) should have a PCRp value of at least 1.5. Find the tolerances for each part

Solution

as we have a nominal lenght of 1.500 inches with a tolerance of +/- 0.050

but we have 3 parts that are essentially identical in terms of manufactugin

so we need to find the tolerances for each part

1.5 / 0.050 = 30

but we have 3 parts so we divided by 3 and that is 10

so the tolerances for each part is 10 inches
