Hi all, Please help guys, I have been at this for hours and still have so much to do.
This is a torsion question but in mathemtical terms can any one solve for value of x???
I keep getting 59.997 but its not right, have taken as far as i can :
Working from:
x : 75x10^6 = 1.57079 (12960000-x^4) 80000 0.33333
We have:
41883.54(12960000-x^4)
I need a value for x. for those with engineering math the original equation is:
T = pi/2*(R1^4-R2^4) * G * Theta/Length
T = 75x10^6
R1 = 60mm
G = 80x10^3
Theta = 1.5 Degrees
Length = 4.5
Need to Find R2
75x10^6 = pi/2 * (60^4 - R2^4) * 80x10^3 * 1.5/4.5
Thanks guys
