A rod `AB` of length `2m` is hinging at point A and its other end B is atteched to a platform on which a point of mass m is kept. Rod rotates about point `A` maintaing angle `theta = 30^(@)` with the vertical in such a way that platform remain horizontal and revolves on the horizontal circular path.If the coeffiicent of staic friction between the block and platform is `mu = 0.1` then find the maximum angular velocity in rad`s^(-1)` of rod so that the block does not slip on the plateform `(g = 10 ms^(-2))`

A block is placed on a horizontal platform.. The system is making horizontal oscillations about a fixed point with a frequency of 0.5Hz . Find the maximum amplitude of oscillation if the block is not to slide on the horizontal platform? (Coefficient of friction between the block and the platform=0.2) (g=10ms^(-2))

A block is placed on a horizontal platform. The system is making horizontal oscillations about a fixed point with a frequency of 0.5 Hz. The maximum amplitude of oscillation if the block is not to side on the horizontal platform, is (Coefficient of friction between the block and the platform = 0.4)

Two particles of mass M=3kg each are kept on a horizontal circular platform on two mutually perpendicular radii at equal distance R=1m from the centre of the table. The particles are connected with a string,which is just taught when the platform is not rotating.Coefficient of friction between the platform and block is mu=0.4 .Then the maximum angular speed (omega in frac{rad}{sec} ) of platform about its centre so that the blocks remain stationary relative to platform is (take g=10.m/s^(2) )
