A mass on the end of a spring undergoes simple harmonic motion with a frequency of 0.5 Hz. If the attached mass is reduced to one quarter of its value, then the new frequency in Hz is
A university library budget committee must reduce exactly five of eight areas of expenditure—I, J, K, L, M, N, O and P—in accordance with the following conditions If both I and O are reduced, P is
A university library budget committee must reduce exactly five of eight areas of expenditure—I, J, K, L, M, N, O and P—in accordance with the following conditions If both I and O are reduced, P is alsoreduced.
If L is reduced, neither N nor O isreduced.
If M is reduced, J is notreduced.
Of the three areas J, K, and N exactly two are reduced Question If both K and N are reduced, which one of the following is a pair of areas neither of which could be reduced
A closely coiled helical spring is acted upon by an axial force. The maximum shear stress developed in the spring is τ . The half of the length of the spring if cut off and the remaining spring is ac
Consider two small blocks, each of mass M, attached to two identical springs. One of the springs is attached to the wall, as shown in the figure. The spring constant of each spring is k. The masses sl
Time period T of simple harmonic motion of a mass m attached to a spring is given by
A spring balance is attached to the ceiling of a lift. A man hangs his bag on the spring and the spring reads 49 N, when the lift is stationary. If the lift moves downward with an acceleration of 5 m/
An open coiled helical compression spring 'A' of mean diameter 50 mm is subjected to an axial load W. Another spring 'B' of mean diameter 25 mm is similar to spring 'A' in all respects. The deflection
A helical spring extends 40 mm when stretched by a force of 10 N, and for tensions up to this value the extension is proportional to the stretching force. Two such springs are joined end to-end and th
A simple spring-mass vibrating system has a natural frequency of fn. If the spring stiffness is halved and the mass is doubled, then the natural frequency will become
Which of the following are the conditions of simple Harmonic motion ?1. The motion is periodic 2. The force is directed towards normal equlibrium position 3. The motion is linear 4. Force is proportio
