A man stands on a weighing machin palced on a horizontal platform the machine reads 50kg. By mean of a suitable mechanism, the platform is made to execute harmonic vibrations up and down with a frequency of 2 vibration per second. What will be the effect on the readin of the weighing machin? Teh amplitude of vibration of platform is 5cm. Take `g=10ms^(-1)`

When a man stands on a weighing machine placed on a horizontal platform, it reads 60 kg . With the help of a suitable mechanism, the platform is made to undergo vertical harmonic vibrations with a frequency of 1 vibration per second. Determine the effect of this S.H.M. on the reading of the weighing machine, The amplitude of vibration of the platform is 4 cm. Take g = 10 m//s^(2) .

A boy is standing on a weighing machine placed on a horizontal platform. The reading of weighing machine is 70 kg. Using a suitable mechanism the platform is made to execute harmonic vibrations with a frequency of 1 vibration per second. Calculate the maximum and minimum force exerted on the boy if the amplitude of vibration of platform is 6 cm.
