Angle of Twist Calculation?

D in = 22

WHAT'S THAT?

For making screws, shaft torque or ion beams ortwisting sisters?

I got 2.541º although not sure?

Please reply!

Stiffness of a circular section in torsion is: Ct= GxJp/L Jp= ∏/32*(de^4-di^4)=9.3429E4 mm^1 ; G= 7.7e4 N/mm^2

Ct= 7.1941 E9 Nmm/rad =1.2556 E8 Nmm/°

φ = T/Ct*L= 6E5*3E3/1.2556E8= 14.336°

The torsion induced stress is τ = 105.96 N/mm^2 It is possible to compute the angle as well from the maximal stress it comes to same value.

Can you show where you plugged the before mentioned data and a simplification of the equation?

angle of twist= TL/JG

J=3.1416(do^4-di^4)/32 ,^=EXP

J=3.1416(33^4-22^4)/32

=3.1416(1185921-234256) mm^4 / 32

=93429.7113 mm^4 or 0.00000009342 m^4

angle of twist=(600 N.m)(3m) / (0.00000009342 m^4)(77GPa)

where:77GPa=77 000 000 000 Pa(N/m^2)

angle of twist=1800 N.m^2 / (0.00000009342 m^4)(77 000 000 000 N/m^2)

angle of twist=1800/7193.34 =0.250231 rad x 180 degrees/phi(3.1416)

angle of twist= 14.3371

thanks!!!

Thank You very much! Now I see...

How the heck did I come-up with 2.451; I tried converting the rads to degrees and came up with 400000 or something along that line!

It seemed a ridiculous # so I submitted the lesser of the two...Hoping does not cut-it? I guess I must Hit The Books!

it usually happens that everyone forgot something,especially topics way back on our school days

i usually forgot such topic so i do scan my pocket formulas and with conversion matter i asked the help of onlineconversion.com

thanks

Did you gentlemen just do someones homework?

Rightly soooo!

Why didn't I think of this when I was in school?

hey agua_doc,im not what you think am i,and were not doin' any homework here

there's a question being ask in these section,im just presenting a small things in here without sending to anybody or to consider myself a good one.

maybe your sicked and needs medical attention

the administrator of these section should block users like you.

maybe its just a sort of freezing temperature that affects you.

Sir, Grow-Up!

And, might I suggest you; apologize puplicly! I did!

/};€ Gotta get rid of this guy!

Christopher, Christopher, Christopher. You have indeed stepped in it here. I encourage you to control yourself. Believe me I know it can be quite difficult.

It's like my Grandpa used to say "Boy, you can think as much as you want. But that talkin' part? That talkin' part needs regulatin' "

peace Bro,its not impolite ,you want everybody to comment, so thats the way i comment to someone's unsound comment.

anyway im not personalizing anybody,its only a comment as what you've said......

there's no need to apologize,but i then say sorry for the comment if you were offended,but then you guys said it is only a comment ,so it is only a comment.
