Question

In an experiment to determine the period of oscillation of a loaded spiral spring, which of the following is NOT a necessary precaution?

A. using small vertical displacements from equilibrium position to set the system in oscillation
B. repeating the timing of oscillations and finding the average
C. using small angular displacements from equilibrium position to set the system in oscillation
D. counting down to zero to start the stop watch in the timing of the oscillations

Answer 1

Answer on Question#55609 - Physics / Mechanics | Relativity

In an experiment to determine the period of oscillation of a loaded spiral spring, which of the following is NOT a necessary precaution?

A. using small vertical displacements from equilibrium position to set the system in oscillation

B. repeating the timing of oscillations and finding the average

C. using small angular displacements from equilibrium position to set the system in oscillation

D. counting down to zero to start the stopwatch in the timing of the oscillations

Solution

A is necessary to set the system in oscillation;

B is necessary to make determination the period of oscillation more accurate;

C is NOT necessary and is wrong, because it is NOT a pendulum;

D is a strange point, why it should be counting down to zero? Looks like it is not necessary however it is not wrong, so, if You have to chose 1 answer, chose C;

Answer: C.
