The apparatus consists of a variable speed D.C. Motor, Driving pulley and Driven

pulley of equal diameter. The pulleys are mounted on input shaft (Motor shaft) and

output shaft. The driven pulley can slide on the base with bearing block to change

initial tension in belt. Brake drum is mounted on output shaft helps to measure power

output. The motor speed is varied by dimmerstat. A two channel RPM Indicator is

provided to measure speeds of driven and driving pullies respectively.
