Dimensional Analysis: Investigation on bifilar suspension Ho Yuk Him (Date of experimentation :20th and 29th October‚ 2010) This paper presents a study on the application of dimensional analysis on the formulation of an equation concerning the periodic time of a rod rotating at an angle about the vertical axis suspended by two strings at each end. We find that period is inversely related to distance between the strings parallel to each other and directly proportional to the both the square root of

Half of this number (0.05 cm) is the uncertainty‚ but because there was uncertainty at either end of the measurement‚ this must be doubled. Therefore the uncertainty in length was 0.1 cm.

After I had the measurements I laid them out in a table. The objects that I measured were a small flask‚ a large flask‚ a tray from a scale‚ a roll of tape‚ a roll of paper towels‚ and a spraycan. By dividing the circumference of the circle by the diameter I was able to

conducting first hand investigations‚ where data is collected‚ quantified or evaluated‚ reliability refers to the consistency of the information‚ validity refers to whether the measurements you are taking are caused by the phenomena you are interested in. This relationship between reliability and validity can be confusing as measurements can be reliable without actually being valid. However‚ they cannot be valid unless reliable. It is easier to be confident of your conclusion when there a limited number
