Please note that these are Multi Part questions. Please answer
all and select the correct options from the given bracket. Thank
you
1)You have obtained the following values: m0= 48 [g],
mw=129 [g], h= 523 [mm], d = 100 [mm], R = 102 [mm], t-without
weights=1.359 [s], t-with weights = 2.196 S. Calculate the
experimental common inertia of loaded pendulum! (-476812.7
g.mm2, -114574.4 g.mm2, 5305632.9g.mm2, 1957900 g.mm2, 22079922
g.mm2, 14258888.5 g.mm2)
2) How many rods does the Oberbecks pendulum cross
have? (6, 8, 1, 2, 4, none)
3) What are correct units for inertia in SI
system? (N/m2, kg.m2, kg.m.s2, kg.s2, g.m2, N.s)
4) How to treat the result if calculated value of
inertia is negative? ( Values of inertia are always
negative, It is normal to have both negative and positive
values of inertia, Ignore minus sign and accept absolute value
as the result, Calculations should be checked for
mistakes)
5) Which of these parts are not from Oberbecks pendulum
lab work experiment? (A string, A timer, Four crossed
rods, A pulley, A ballistic pendulum)
6) What does symbol "h" represent in equation
I=m0r^2.(gt^2/2h -1) ----options (Height of the weight
which is pulling the string/thread, Height traveled by the weight
which is pulling the string/thread, Total height of the laboratory
device, Length of one rod on Oberbecks pendulums cross, Height of
rotational axis of Oberbecks pendulums cross, Height of the
Oberbecks pendulum above the sea level)
