Simply cannot get my calculator to give me the correct answer!?
I'm going through a worked example I did in a tutorial and cannot get the same answer we did in class with my calc!?
Damping ratio = the square root of E2 / 4∏2 n2 E2
Where E=2.526 n=2
I'm getting 0.0796 , doing 4x(pie2) and 0.0398 doing (4xpie)2
The answer from tutorial is 0.1971 and is deffinately correct.
I've broken each bit down and worked it out separately and put it into the calc then in the simplified way but still I'm not getting the right answer :(
