15.20 The belt shown moves over two pulleys without slipping. Pulley A starts from rest with a A clockwise angular acceleration defined by the relation a = 120 — 0.002 ow”, where a is expressed " in rad/s? and @ is expressed in rad/s. Determine, after one-half revolution of pulley A, (a) the magnitude of the acceleration of point B on the belt, (b) the acceleration of point P on pulley C. did db: 2 od? a Ate dt 2 wx (I 2. | (i) 2/20 rad x 4,002 | wees g* We, gocoot dle Up Tank LO% 2) pe Bs Fook (#2) | Oe ai wo ° = a= 2 : pie Mt + wall ash yeu te do This path bat OE) aie / fi 2 ES plus in (2) l= 244 af, pag in O) ogo KV, rg 2 OME T tt gn” XpoX Ler + A, NOL od jisb A Lyn 2 NST FHF = OS pea = Ne? gr A a - 2a 4h rad Var? _/6 254 Ms 1 Spe got [He tangent KrF i K = Age = [Gazy|- BY port ACL ~ RA ry + We2* Vpe wok Bp, KeoX ape val m meen” * ad Vp. = We, * Lpe Lpn 7 2: My, * -164,64 , + Vp >~ 29 * a Ap, 2-02) - F424 52 ny
