| The weight of a mass hung from a single spring scale is compared to the weight shown on a spring scale between two masses over pulleys. | This is a two part demo though just one of the parts may be chosen. A mass is suspended from a string connected to a string-suspended spring scale. The string suspending the scale is then run over a pulley and attached to another spring scale which is held by the instructor. The registered tension is the same in both cases. |

Abstract:
This is a two part demo though just one of the parts may be chosen. A mass is suspended from a string connected to a string-suspended spring scale. The string suspending the scale is then run over a pulley and attached to another spring scale which is held by the instructor. The registered tension is the same in both cases.
