A heavy mass m is hanging from a sting in equilibrium without breaking it. When this same mass is set into oscillation, the string breaks, Explain.

The period of oscillation of a mass m suspended from a spring of negligible mass is T. If along with it another mass m is also suspended the period of oscillation will now be……..

Periodic time of oscillation T_1 is obtained when a mass is suspended from a spring if another spring is used with same mass then periodic time of oscillation is T_2 . Now if this mass is suspended from series combination of above spring then calculate the time period.

A heavy mass is attached to a thin wire and is whirled in a vertical circle. The wire is most likely to break

A string of mass per unit length mu is clamped at both ends such that one end of the string is at x = 0 and the other is at x =l . When string vibrates in fundamental mode, amplitude of the midpoint O of the string is a, tension in a, tension in the string is T and amplitude of vibration is A. Find the total oscillation energy stored in the string.

A boy of mass 40 kg is hanging from the horizontal branch of a tree. The tension in his arms is minimum when the angle between the arms is:-

Let T_(1)" and "T_(2) be the time periods of spring A and B when mass M is suspended from the end of the spring. If both springs are taken in series and the same mass M is suspended from the series combination, the time period is T, then

A bob of mass 0.1 kg hung from the ceiling of a room by a string 2 m long is set into oscillation. The speed of the bob at its mean position is 1 m s^(-1) . What is the trajectory of the bob if the string is cut when the bob is (a) at one of its extreme positions, (b) at its mean position.

When a mass m attached to a spring it oscillates with period 4s. When an additional mass of 2 kg is attached to a spring, time period increases by 1s. The value of m is :-

Two identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in Fig. 14.14. Show that when the mass is displaced from its equilibrium position on either side, it executes a simple harmonic motion. Find the period of oscillations.

Two point masses m_1 and m_2 are connected by a spring of natural length l_0 . The spring is compressed such that the two point masses touch each other and then they are fastened by a string. Then the system is moved with a velocity v_0 along positive x-axis. When the system reached the origin, the string breaks (t=0) . The position of the point mass m_1 is given by x_1=v_0t-A(1-cos omegat) where A and omega are constants. Find the position of the second block as a function of time. Also, find the relation between A and l_0 .
