An Asymmetrical Static Equilibrium Physics Problem Involving Pulleys and Hanging Masses
An interesting phenomenon in physics, and physics education, is the simplicity of symmetric situations, compared to the complexity of similar situations which are, instead, asymmetrical. Students generally learn the symmetrical versions first, such as this static equilibrium problem, with the … Continue reading
