Equilibrium and Pulleys: String and Pulley June 23, 2009 Purpose In this experiment, students will develop physical models to describe force interactions  for strings and pulleys. Hypothesis A string and pulley can be used to transmit or redirect a force without changing it if the  string is light enough. The string will transmit a force between the two objects without  significantly affecting the magnitude of that force if it is light enough. Materials -several spring scales -light, low-stretch strings -several light, low-friction pulleys
