Q.1
What is a photo-reflective tachometer used for?
  • Measures the torque on a sheave.
  • Measures the speed of a sheave.
  • Takes a picture of a sheave as it rotates.
  • Measures the wear on a belt.
  • Examines the surface of a sheave.
Q.2
Which of these belts are well suited for timing mechanisms?
  • Flat belt
  • V-belt
  • Synchronous belt
  • Multiple V-Belt
  • All types can be used
Q.3
Power is transferred between an electric motor and a pump with a belt drive. Calculate the required driven sheave pitch diameter and belt length if the motor and pump shafts areinches apart and the pump shaft must rotate atr/minute. The driving sheave is installed directly on the motor shaft and has a pitch diameter of 5 inches. The plate on the motor indicates a nominal speed ofr/minute.
  • Driven sheave pitch diameter is 2.8 inches and belt length is 52.2 inches.
  • Driven sheave pitch diameter is 9 inches and belt length is 52.2 inches.
  • Driven sheave pitch diameter is 9 inches and belt length is 62 inches.
  • Driven sheave pitch diameter is 2.8 inches and belt length is 62 inches.
  • Impossible to tell from the given data
