A circular disc of radius b has a hole of radius a at its centre (see figure) if the mass per unit area of the disc varies as `((sigma_(0))/(r))` then the radius of gyration of the disc about its axis passing through the centre is
The radius of of disc is 2 m the radius of gyration of disc about an axis passing through its diameter is
The radius of gyration of a disc about an axis coinciding with a tangent in its plane is
Calculate the radius of gyration of a circular disc about its diameter.
A uniform disc (of mass M and radius a ) has a hole (of radius b ) drilled through it. The centre of the hole is at a distance c from the centre of the original disc. What is the moment of inertia of the disc about an axis through the centre of the disc and perpendicular to its plane ?
From a disc of radius R and mass m, a circular hole of diamter R, whose rim passes through the centre is cut. What is the moment of inertia of the remaining part of the disc about a perpendicular axis, passing through the centre?
From a disc of radius R and mass M , a circular hole of diameter R , whose rim passes through the centre is cut. What is the moment of inertia of remaining part of the disc about a perependicular axis, passing through the centre ?
There is a uniform circular disc of mass 10kg & radius 2 meter. Calculate the radius of gyration if it is rotating about an axis passing through its centre & perpendicular to its plane
