Explanation:

Two shafts of different materials can be joined together is two ways:

Shafts in series:

  • Two shafts are said to be joined in series if the driving torque is applied at one end and the resisting torque at the other end
  • For shafts in series, both the shafts carry the same torque T and the total angle of twist at the resisting end is the sum of separate angles of twist of two shafts
  • T1 = T2

Shafts in parallel:

  • If two or more shafts are rigidly fixed together such that the applied torque is shared between them then the composite shaft so formed is said to be connected in parallel
  • Angle of twist for both the shafts is the same
  • θ1 = θand T = T1 + T2
