Moments Of Inertia Abstract: Through experimentation the principles of inertia are observed. Inertia is the resistance to changes in state of rotational motion. It depends on the mass of the object being rotated and its shape and size, along with the center of gravity. Initially, the inertia caused by the rotating apparatus must be found. If a string is attached around the circular apparatus with a pulley with weight attached then it would normally fall at the rate of gravity (9.8 m/s^2).
The second part of the procedure holds F constant and investigates the relationship of a to m by altering the total mass of the system. Again, based on the equation a = F/m, acceleration and mass should be inversely related to each other. m = k/a and a = k/m. 2. PROCEDURE 2.1 Equipment & Materials The key piece of equipment used in this investigation is the Atwood machine.
Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the ball falling down. That value will be compared to the gravity value to see how closely related they are. Introduction The formal lab “Uniform Acceleration”, studies uniform acceleration by rolling a ball down a ramp and dropping an object to calculate its acceleration. Also this lab teaches about measurement uncertainty can be calculated using the percent error equation.
A transmission transfers the power created by the engine to the wheels through a driveshaft and axle. B. Being able to change the gears manually lets you change the torque on the wheels depending on the speed at which you are traveling, torque is a measure of how much a force acting on an object causes that object to rotate. C. Each gear has its own ratio of rpm, which is revolutions per minute, which is a measure of the frequency of a rotation, it annotates the number of turns completed in one minute around a fixed axis. D. The clutch is a mechanical device that provides for the transmission of power ( usually motion) from one component (the driving member) to another (the driven member) when engaged, but can be disengaged.
Lab 7: “Newton’s Second Law” Newton’s Second Law Purpose: To find the graphical and mathematical relationship between the Net forces applied to an object, its mass and acceleration. Variables: Independent: -Hanging mass Dependent: -Acceleration -Force pulling on cart Materials: * * Dynamic Cart with pegs * Force Sensor * Motion Detector * Computer with Logger Pro * Lab Pro * Ramp with Pulley * Mass Sets * String Procedure: 1. Assemble the Ramp and pulley system as shown. Attach proper length of String to the Force Sensor, and add a loop at the opposite end for attachment of various weights. 2.
There were four types of collisions performed. The first was with a light spring, the second was with a heavy spring, the third was with an airbag, and the last was with not air bag. The forces of the cart were measured using a computer. Once the time was started, the cart was tarred and then it was pushed down the track. The computer measured its speed and the impact forced of the collision.
What are the steps necessary to fix the problem that cause the data loss? Verify what caused the loss by reading the logs. Determine the fix for the issue. Reimage the computer. Restore the computer to last backup state and disable the issue that caused the data loss.
We place an analog ground and connect the circuit from the source through the resistors and ground as shown below. [pic] We then place and connect the virtual oscilloscope across R1 and R2 as show in the figure above. We also place a voltmeter across our power source and across R2, also shown above. We open the oscilloscope window to view the graph and run the simulation for a moment to collect data, shown below. [pic] Using the oscilloscope is not as precise as a digital measure as you must visually count the lines or boxes to estimate the values.
IT104 Pre Lab: Use the Prebuilt Virtual Machine for This Course These instructions describe how to use the VMware Player to launch the preinstalled virtual machine for the labs in this course: 1. Copy the preinstalled virtual machine on to your USB external pocket hard drive. a. Create a folder on your USB portable hard drive to store all the virtual machines used for the curriculum. You may name the folder something like “Virtual Machines for My Courses”, and create subfolders in it by the course number.
