MEASURING THE HEIGHT FROM THE FLOOR TO THE CABLE TRUNKING Aim The aim of this experiment is to use measurements on a pendulum to find the height of the overhead cable trunking in order to access the viability of using the method for measuring the height of a bridge. Apparatus * Pendulum * Length of string * Two small wood blocks * Metre Rule * Stopwatch * Retord Stand * Clamp * One large Wood Block Apparatus Specification Apparatus Range Of Measurement Maximum Measurement Minimum Measurement Metre Rule 0m - 1.000m 0.001m 1.000m Stopwatch 0.01 sec - 356400.00 sec 356400.00 sec 0.01 sec Method The three wooden blocks are used to hang the pendulum from the overhead cable trunking. Initially the length of the string is measured from the place where the string starts hanging from the trunking to the middle of the bob. Initially keeping in mind the design and the procedure of the experiment the values of the height of the string are noted. The bob is set to the initial...
