5/167 The slider A oscillates in the slot about the neutral position O with a frequency of 2 cycles per second and an amplitude xmax of 50 mm so that its dis placement in millimeters may be written x 50 sin 4mt where t is the time in seconds. The disk, in turn, is set into angular oscillation about O with a frequency of 4 cycles per second and an amplitude 0max 0.20 rad. The angular displace- ment is thus given by 0 0.20 sin 8mt. Calculate the acceleration of A for the positions (a) x 0 with positive and (b) x 50 mm. Ans. (a) a 6.32j m/s2 (b) aA9.16i m/s y x A x Problem 5/167
