What is the moment of inertia for a hoop?
The moment of inertia for a hoop is equal to its mass multiplied by the square of its radius.
How do you calculate radius of gyration for circular section of pile?
The radius of gyration (r_g) for a circular section of a pile can be calculated using the formula: ( r_g = \sqrt{\frac{I}{A}} ), where ( I ) is the moment of inertia of the circular section and ( A ) is its cross-sectional area. For a solid circular section, the moment of inertia is given by ( I = \frac{\pi d^4}{64} ), where ( d ) is the diameter of the pile. The cross-sectional area ( A ) is calculated as ( A = \frac{\pi d^2}{4} ). Substituting these values into the radius of gyration formula provides the desired result.
