Figure 1. Torque between two residues.
The torsional inertia is determined from the length of the rotational
radius and the mass of the object. The components of torque in the
polypeptide chain are displayed.
Figure 2. Difference of torque among various bond angles.
The magnitude of the torque varies according to the angles of bending of
the rotating from stalled residues. The torque is maximized as it turns
orthogonally while it vanishes when it turns in parallel.
