    Single Degree-of-Freedom Systems

    An SDOF system (m = 20 kg, k = 350 N/m) is given an initial displacement of 10 mm and initial velocity of 100 mm/s. (a) Find the natural frequency; (b) the period of vibration; (c) the amplitude of vibration; and (d) the time at which the third maximum peak occurs. Ans: 0.666 Hz; 1.502 sec...

    Single Degree-of-Freedom Problem

    1.A 3 m high, 8 m wide single-bay single-storey frame is rigidly jointed with a beam of mass 5,000 kg and columns of negligible mass and stiffness of EIc = 4.5×103 kNm2. Calculate the natural frequency in lateral vibration and its period. Find the force required to deflect the frame 25 mm...
