(Dynamic simulation) Torque / angle of twist for bending frequency

[Anonymous]

Hello All,

I have torsional stiffness of a body (2200 kN.m/rad) and i want to find the (T) torque or (phi) angle of twist of the body. 

any insight on how to find this?

From k = (T/Phi)

K= torsional stiffness (Given)

T=Torque (need to Figure out)

Phi: Angle of twist. (need to Figure out)

Dimensions of the model:

L =12.5 m; B= 2.65 m; H= 2.32 m.

mass m= 15000 kg; 

any help appreciated.

Actually i need to find Bending frequency of the model. If i have the above said quantities i can find the bending frequency.

Hello Zhang,

Thank you for the response. I understand the concept.

but please look into my question again.

------------------------------------------------------>

From k = (T/Phi)

K= torsional stiffness (Given)

T=Torque (?)

Phi: Angle of twist. (?)

Dimensions of the model:

L =12.5 m; B= 2.65 m; H= 2.32 m.

mass m= 15000 kg; 

I need to figure out torque or angle of twist.

please share your insight.

Thanks.
