Determine the linear and angular acceleration of the disks. A diagram is illustrated as having a small disk (radius 1m) with a rope hanging on its edge with a mass of 12 kg attached to it. Another pulley disk (radius 2m) surrounds the smaller and first one; it has a rope attached to a 4 kg mass. This is what I have so far: T1 - m1g = m1a1 = t1-117.6 = 12a1 m2g - T2 = m2a2 = 2 [39.2 - T2 = 4a2] = 78.4 - 2T2=8a2 --- In order to find the accel., I calculated the velocity from the radii and distance using arc length. d2= 2(theta) d1= 1(theta) d2/d1= 2(theta) d2=2a1 v2=2v1 a2=2a1 a(tangential)= (alpha)r (alpha= angular accel.) a2=2(alpha) 2a1=2(alpha) (alpha) = a1 T1 - 177.6 = 12a1 78.4 - 2T2 = 8a2=8*2(alpha)=16(alpha) + 2T2 - T1 = 4a1 ___________________________________ -39.2 = 32a1 a1= -1.225 a2= 2(-1.225) Having done that....are the objects decelerating not accelerating? And have I completed all the steps correctly?
