  hey guys tell me how to determine the following:
  consider two v-pulleys connected by a v belt. the speed at which the driving pulley rotates is known . how do we determine the torque on the driver pulley as well as the speed of the driven pulley and the torque transmitted to the driven pulley by the driver. we know : the diameters of both the pulleys
  the angle of slip of the belt

  This may help:

  server trouble. Multiple posts.

  Yeah, even I faced one!!! 😔 #-Link-Snipped-#, please look into this...

  I deleted the posts, that's why.

  To determine the torque on the driver pulley you must first find the tensions T1 and T2 on the belt.
  Torque = (T1-T2)*(Radius of the driver pulley)
  To determine Speed of the driven:
  Use the ratio: Speed of Driver * Radius of Driver = Speed of Driven * Radius of Driven
  i.e. v1r1 = v2r2

  thanx a lot dude, now can u tell me how to determine the belt tensions

  e^(u)(theta) = (T1-Tc)/(T2-Tc)
  where T1 is the maximum tension which the belt is specified for
  u = coefficient of friction
  Tc = mv^2
  m = mass of the belt
  v =RPM*(2pie/60)*radius of driver
  
  You can now find T2 knowing T1 and Tc.
  be sure to use standard units and theta is in radians

  thanx again. but the problem is i do not know T1 either . now what to do

  I would suggest you search the manufacturer's specifications. Call your supplier or visit their website.
  I am not sure but check on the belt itself to see if there is any indication there.
