Mike,

Will you email me the spreadsheet you created. I am also desinging a torsion spring for a flight attendant seat.

Thanks
: I created a small spreadsheet to calculate the parameters of a single helical torsion spring.
: Input - wire diameter, mean coil diameter, #coils, material constants
: Output - max torque, twist angle, spring rate, diameter reduction
: It uses standard formulae from a Shigley and Mischke textbook. Email me and I will send the spreadsheet to you.
