Unformatted text preview: the time period T . Formulae used are applicable only for small oscillations. 3. Place the regular body at the center of the plate and measure the frequency of oscillations again, by timing the number of oscillations as before for measuring the time period T l. 28 4. Replace the regular body by the given object (irregular body) and measure the time period of oscillation T x.. Observation Table S. NO System Number of oscillations Time for 30 oscillations (sec) Time Period (sec) Average Time period (sec) 1. Bare system (Repeat several times) T 0 = 2. With Reg.body (Repeat Several times) T 1 = 3. With Irreg. body (Repeat Several times) T X = Reference: Haliday, Resnick and Walker, Fundamentals of Physics, 6 th Ed.
