诚信关乎个人一生,公平竞争赢得尊重。 以下行为是严重作弊行为,学校将给予留校察看或开除学籍处分,1.替他人考试或由他人替考,2.通讯工具作弊.3.团伙作弊。 2. (15 points) A body of mass is m kg which is suspended by a spring of stiffness of 1000N/m and dashpot of damping constant 1000Ns/m. Vibration is excited by a harmonic force of amplitude m N and a frequency of m Hz. Calculate (Note: values of m equal to ID which is your class number). (1) the amplitude of the displacement for the mass; (2) the phase angle between the displacement and the excitation force. IN C A) Fig. 1
