The frame shown consists of a steel beam welded rigidly to two vertical channels . An eccentric exciter weighing 350 N is attached to the beam , which weighs 15 KN and is used to excite the frame . The unbalance weight of the exciter is 30 N and it has an eccentricity of 7 cm . By varying the rotational speed of the exciter until resonance occurs , the maximum horizontal amplitude was found to be 5 mm . Assuming no bending on the beam and considering the channels to be completely fixed at C and D ( see Figure ( 1 ) ) , determine , ( a ) The natural frequency in Hz . ( b ) The damping factor . ( c ) The magnification factor at resonance . ( d ) Discuss whether this values in ( a ) , ( b ) and ( c ) are better for the structure if it is high or low .

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
