Question

1. A metronome is a simple pendulum. Why does changing the position of the mass on an arm change the speed of the beats/clicks produced?

2. Is it better to use a spring with a high or low value for k and why?

Answer 1

1 )

Introduction

A metronome is any device that produces typical, metrical ticks (beats, clicks) —

settable in beats each minutes. It is used by specialists to help keep a predictable beat, and used by

as a standard cadence reference, to demonstrate the arranged beat for the piece.

The arrangement of metronome incorporates SHM.

Working of metronome

A mechanical metronome uses a versatile load on the completion of an irritated pendulum bar to change the beat.

A second, settled weight is on the base of the pendulum turn, concealed inside the metronome case.

That is the reason a mechanical metronome is generally called a twofold weighted pendulum.

The pendulum subsequently performs SHM ,

which has a steady period. Thusly, the metronome can for the most part beat at the cadence set.

2 )

using equation

F = - k x

so here F is proportional to k

so if we want to make a force high or low based on the spring constant.

so it is better that the spring can be used.
