Moment of inertia of a hollow shaft
Web6.7 POLAR MODULUS. Polar modulus is defined as the ratio of the polar moment of inertia to the radius of the shaft. It is also called as torsional section modulus. It is denoted by … WebThis involves an integral from z=0 to z=L. For any given disk at distance z from the x axis, using the parallel axis theorem gives the moment of inertia about the x axis. Now expressing the mass element dm in terms of z, we can integrate over the length of the cylinder. This form can be seen to be plausible it you note that it is the sum of the ...
