stress= 2659.588351 psi , force = 522.209 psi/in^2 , area= 0.1963 in^2 , accuracy of load cell = 0.005 in , accuracy of calliper = 0.001 in ,

•What is the uncertainty in this stress calculation?

Determine which tool (load-cell or calipers) most affects stress calculation

*Could you please show all steps because i am going to do it in Excle

Thanks in advance

Expert Solution

hey first of all here you need to find an uncertainty of stress which not directly measure but its calculated by some arithmetic operation from other measured quantity. If your arithmetic operation contains only addition or subtraction then you directly add the measured uncertainty. but when you have multiplication and division in your arithmetic operation you need to calculate percentage relative uncertainty because in multiplication and division uncertainty always added to one another. which you can see in the calculation image below.

If you have any further query feel free to comment below. Otherwise, Thank you for THUMS UP.....!!!!
