medical alloys may have varying expansion coefficients
... where did the 1.30E-7 come from?
A steel rod is 2.55 cm long at 16 o C in an operating room. It is placed in a patient's leg where it rises to 37 o C. What will the change in length be?
coefficient of linear expansion for steel 13.0 x10^-6
I am getting .0006915 but the answer is .000643 according to book
What am I doing wrong or does the book have a misprint?
13.0x10^-6 x 2.55 cm x (37-16) =.0006915
