The objective of this experiment was to study different pulley systems and determine their actual and Theoretical Mechanical Advantages and there efficiency. This was accomplished by setting up various pulley arrangements on a stable platform these systems consisted of 3 and 4 pulleys in a block and tackle like fashion. The loads the pulleys were tested with, weighed in the range 250 -500 grams and an effort required to balance these loads was determined through experimentation.
