The body is sometimes acted by two or three force members and we need to find the radius of gyration for the same. The difference between the two and the three force members is:

The former is collinear and the latter is parallel

The former is parallel and the latter is perpendicular

The former is perpendicular and the latter is collinear

The former is acting on two points in the body while the latter is on three points

If any external force also is applied on the structure and we are determining radius of gyration then what should we consider?

The net force will act at the centroid of the structure only

The net load will not be formed as all the forces will be cancelled

The net force will act on the base of the loading horizontally

The net force will not to be considered, there would be a net force of the distribution, rest will be the external forces

If the non-Uniform loading is of the type of parabola then for calculating the radius of gyration?

The net load will not be formed as all the forces will be cancelled

The net force will act the centre of the parabola

The net force will act on the base of the loading horizontally
