A Study of pulleys .
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. These Results were …showed first 75 words of 1148 total…

Sample calculations
To determine TMA
Determine number of ropes carrying the load (forces acting on the load)
In this case the TMA is 4
To determine AMA
AMA=Force load /Force effort
Force=Mass*g
AMA = Mass load / Mass effort
= 0.4618g /0.126g
=3.67
*Note AMA for the Lab was done using a graph and graphing software to find the slope this method is only for single pieces of data
To determine efficiency
AMA/TMA
2.54/3.00* %100 =
