Define radius of gyration

Posted by Taranvir Singh 8 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Himanshu Singhal 8 years, 3 months ago

Radius of gyration or gyradius refers to distribution of the components of an object around an axis. In terms of [mass moment of inertia], it is the perpendicular distance from the axis of rotation to a point mass (of mass, m) that gives an equivalent inertia to the original object(s) (of mass, m). The nature of the object does not affect the concept, which applies equally to a surface, a bulk mass, or an ensemble of points.

Mathematically the radius of gyration is the root mean square distance of the object's parts from either its center of mass or a given axis, depending on the relevant application.It is actually the perpendicular distance from point mass to the axis of rotation.

Total distance=s =ut+1/2at^2 where u=5m/s a=2m/s^2 & t=10s S10th=u+a/2(2*n -1) where a=2 m/s^2 n=10s (1) V at 9th sec. =u at 10th sec. v= u + at where u=5 a=2 &t=9 This v is initial velocity of 10th sec. and can be put into (1) eq. Hence ,Snth can be calculated

ANSWER

A train is travelling at the speed of 180km/hr. In order to trap superman Rohan has broken the rail tracks. Unaware of Rohan evil intension, superman tries to stop the train by pushing it in opp. Direction right at the moment when the train is 300m away from the crack in track, superman is applying a deceleration of 5m/s2. Just after 2 sec a bullet laced with kryptonite hits superman which incapacitates him for a while. How long has superman got to remove the bullet?
