Understanding Torsion Angle in Practical Applications

In summary, the conversation is about clarification regarding torsion angle. The textbook definition of torsion angle involves one end of a shaft being rigidly fixed while the other end experiences a load. However, in practical applications where the shaft is coupled with a motor and a line shaft, the concept of theta may not be applicable as the line shaft is supported at both ends and has rotational freedom. The layout of the shafts in this scenario is that 25 shafts are coupled together with a length of 1m and torque is transmitted in between. The question is whether the standard formula can be used in this situation and if the length of the shaft can be considered as the total length when there are multiple shafts joined by rigid couplings

Dear all,

I need clarification regarding torsion angle.
In textbook torsion angle is explaining that one end is rigidly fixed another end is giving load.In this we can visualize theta where as practical application motor coupled with line(transmitting lengthy shaft)shaft i cannot visualize theta becoz in this while transmitting load line shaft is properly supported at the ends& in between since rotatoinal free at both ends will it theta available?

Note:
our layout is shaft is coupled to one together in between load is transmitted
No of shafts -25,shaft(one shaft) length-1m,In between torque is transmitted

if we used standard formula will that is accepted one? also more than

25 shaft are copuled together and it joining by rigid couplings can we

take Length as total length?


Thanks for the replies

use the net torque.

the example where one end of the loaded shaft is fixed is equivalent to a free end with a reaction torque (moment).

1. What is torsion angle and why is it important in practical applications?

Torsion angle, also known as dihedral angle, is the angle between two planes in a molecule. It is important in practical applications because it determines the spatial arrangement and conformation of molecules, which affects their physical and chemical properties.

2. How is torsion angle measured in a molecule?

Torsion angle is measured by selecting four consecutive atoms in a molecule and calculating the angle between the planes formed by the first three atoms and the last three atoms.

3. What are some practical applications of understanding torsion angle?

Understanding torsion angle is crucial in drug design and discovery, as it helps predict the binding affinity and selectivity of molecules to target proteins. It is also important in the study of protein folding and enzymatic reactions.

4. How does torsion angle affect molecular stability?

Torsion angle plays a role in the overall stability of a molecule by determining the spatial arrangement of its constituent atoms. It can affect the strength of intermolecular forces and the overall shape of the molecule, which in turn affects its stability.

5. Can torsion angle be manipulated in practical applications?

Yes, torsion angle can be manipulated in practical applications through the use of molecular modeling and simulations. By altering the torsion angle, scientists can predict and design molecules with specific properties for different applications.
