Investigation of the Factors Affecting the Period of Vibration of a Weighted Cantilever

The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

Introduction: Today scientists put acquired data into a form of a graph. This said graph is designed to help make predictions and furthermore, study and understand the experiment and its contents at hand. The Graphing and Estimating lab involves just that. The lab is designed to collect data from several tests involving burn time of a candle.

After the positions were recorded for frequencies 1,803 Hz, 2,402 Hz, 3,002 Hz, 3,600 Hz, and 4,201 Hz, the wavelength was determined for each. This was done by subtracting the initial position from the final position (position final–position initial=wavelength). Using the calculated wavelength, the speed of sound in air at each frequency was determined by multiplying the wavelength by the frequency (speed of sound=wavelength x frequency). By adding the five speed values and dividing by the number of speeds, the average speed of sound was calculated. Then 344 m/s was used as the accepted

In this model, T2 is the orbital period squared, M is the mass ratio, L is the length of the string and g represents the acceleration due to gravity.

-“The wavelength is 0.20 s.” This is wrong because wavelength’s unit is meter and it measures the distance between two adjacent locations in the disturbance, not the time one particle takes to finish one vibration.

The givens and assumptions are all of the values included in the above equation. The equation above also highlights what we needed to find, the discrete dynamical system, and the plan was to make assumptions, analyze the givens, and substitute all the given values into the general discrete dynamical system equation.

10. How does varying the frequency effect contraction force? Which interval caused the greatest contraction?

It may not be a good idea to describe a population by its average (blue line on trajectory summery), as the model takes into account the standard deviation (indicated by upper and lower error bar thresholds). This standard deviation displays the equal probability that a population will reach these upper and lower abundances over the course of the population model. It is important to realise this difference as over the course of a population model (25 years), the standard deviation error thresholds may allow the population to become extinct or it may allow it to explode to excessive numbers which is a huge population range between upper and lower figures. Each time a model is simulated, the average abundances will be different but will remain within the standard deviation outliers.

Musicians know that all vibrating objects make sounds. Frequency measure how many times a string vibrates up and down. If a musician changed the length of the string, it also changed the frequency. High frequency will always equal a high pitch. When an octave is increased the frequency will double. Pythagoras discovered different sounds could be made with different weight and vibrations. Due this discovery, they also realized pitch could be controlled by the length of the string.

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

where smax is the maximum displacement or displacement amplitude, k is the angular wave number, and w is the angular frequency of the piston.

A simple pendulum consists of a mass that is attached to a string of length ‘L’ that is fixed to a point, in this case, a cork suspended by a clamp stand. This allows the mass to be suspended vertically downwards and allows it to be displayed at an angle that it swings. A period ‘T’ of oscillation is the time required for one complete swing. For this to happen ideally its mass must swing from an angle that is

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.

The values denoted by an * are values that were inserted during the investigation for this project. The process to find the values of Intensity with a given Intensity Level was already mentioned, but the process in order to find Intensity Level by knowing the Intensity of a sound was not. In order to find intensity level beta (b) from the equation one just takes the logarithm of and multiplies it by ten. The finding of the intensity level of a quiet radio by knowing its intensity will be the example to test the method.
