THE ANSWER IS ?

Consider a pulley as shown. A string is placed on the pulley. The string is massless and the pulley has friction. Consider the two tensions T1 and T2, T1>T2 The coefficient of friction is k. Find the ratio T1/T2 when the string is just about to slip over the pulley.

DETAILS

  • k = 1/pi
  • Theta = pi (rad)
  • pi = 3.14159265
  • e = 2.71
