299) A shaft of mass (m_c)and stiffness (s) is fixed at one end and carries a mass (m) at the other end. The natural frequency of its transverse vibration is same as for longitudinal vibration.

301) The stress induced in a body will be shear stress, when it is subjected to

302) A machine mounted on a single coil spring has a period of free vibration of t_p . If the spring is cut into four equal parts and placed in parallel and the machine is mounted on them, then the period of free vibration of the new system wil

303) When a body is subjected to longitudinal vibrations, the stress induced in a body will be tensile or compressive stress.

304) If the number of links in a mechanism are equal to l, then the number of possible inversions are equal to
