Question
I need help with question 5. From my data there does not seem to be a significant difference in the period between D &F.. is there supposed to be one because gravity is now acting on the system in figure 2 but not in figure 1? What would the force diagram look like? Hence if T is plotted along the y axis and m is plotted along the x axis, the resulting graph should be a straight line with a slope 4m2 And a y intercept =0,0798 (1869 042-199-5 mo=- Procedure: 4 A. Attach the inertia balance to the table with a C clamp so that it will oscillate in the horizontal plane. B. Put a load of two 100 g weights on the platform and determine the time for 100 oscillations. Be sure that the weights are in the center of the platform. By using small amplitudes and waiting until several oscillations have occurred before timing, there will be no slippage of the weights on the platform. Repeat for loads of 300, 400, 500 and 600 g weights. Place the unknown mass in the hole of the platform. Record the time for 100 oscillations. Weigh the unknown mass on a gravitational balance. Suspend the "unknown" by a long cord so that it is raised slightly above the platform, and its mass no longer rests on the platform. The suspending cord should be at least a meter irn length, and the point of suspension should be directly above the hole in the platform Determine the period of the balance. C. D. MuCD) E. F. Clamp the balance to the under edge of the bench with the balance extending downward. (Figure 2). Load the platform with the "unknown", use a little tape to secure it and determine the period.Explanation / Answer
5. for a spring mass system osscilating in horizontal plane the time period is given by
T = 2*pi*sqroot(m/k)
now when this system osscialtes in the vertical plane, the equilibrium position of the osscialtion shifts by certian amount as given by the weight of the mass.
but the time period is still given by 2*pi*sqrok(m/k)
since gravity has no role to play in the time period of osscialtion of a spring mass ssystem the tim period calculated in steps D and F should come to be exaclty the same
in practical application there should not be much difference between the two values
