For example, if the natural resonant frequency is multiplied by 3, there will be 2 antinodes. Many times friction will be ignored in a lab, but with this simple experiment there is no friction present. The results in our lab experiment remained, for the most part, consistent; however, we noticed several sources of error. This should be shown by the following experiments. http://phabletkeyboards.com/sources-of/sources-of-error-in-static-equilibrium-lab.php
The lone real life concept that can be taken away from this lab, is the property of inertia. Rounding numbers Pointy · 9 years ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse Add your answer Static equilibrium lab? Torque is defined as the tendency of an object to rotate. Trial 6 is also frequently used in the real world.
Get it on the web or iPad! Errors in reading of dimensions 3. More questions Forces and static Equilibrium!? font.
Completing the objective proved harder than anticipated. E. The system returned: (22) Invalid argument The remote host or network may be down. Torque Formula If you multiply 1/(wanted slope/variable), then all of the numbers will be correct.
This conclusion makes sense because a heavier mass usually vibrates much slower than a light mass would because it has a greater inertia than a light mass, thus resisting the change Torque Lab Report Data: Mass of Figure Red (kg) Mass of Figure Silver (kg) 1 0.02394 0.02157 2 0.01016 0.00924 3 0.00404 0.00404 4 0.00142 0.00131 5 0.00058 0.00053 Dowel Mass (kg) Dowel Length In the second though, the spring phases in and out of equilibrium as it moves along its period. No, create an account now.
We were able to have some of the dowels hang off center but still stay balanced. Newer Than: Search this thread only Search this forum only Display results as threads More...

What is the efficiency of the engine? In this situation, in order to balance the seesaw, the heavier of the siblings must sit closer to the pivot point than the lighter of the siblings. Torque Lab Sources Of Error Through these various methods of experimentation and measurement, we were able to fundamentally prove the ideas behind torque and equilibrium, thus demonstrating their legitimacy throughout the field of physics. Static Equilibrium Lab Conclusion Because of this, the COM must be included as a mass of sorts on one side of the pivot point (included with its own force and distance from the pivot point).

Our data confirms the expected dependence of the period (T) on the lengths (L) of a pendulum. brainpushups, Sep 1, 2015 (Want to reply to this thread? Rotational Equilibrium
Assemble the mobile by drilling small holes at the ends of each dowel and at the tops and bottoms of each dowel. threshold: pts Edit criterion description [ Select ] Save this comment for reuse pts / 5.0 pts -- Procedures 43_594 view longer description Diagram, pictures (camera or drawn), free body, Buy two sets of nesting dolls, each containing 5 different "layers". 3. my review here The particle must be acted upon by a force, which must be resulting from the displacement of the particle from its equilibrium position.
Data: Spring Constant Lab Hypothesis: Because of the spring constant's ability to be expressed through finding the period of its movement as well as the length that it stretches, the spring Answer Questions Physics Problem URGENT!? Data: Sample picture of Calculation 4: In this diagram, the two forces acting upon the system are the ruler's center of mass in the clockwise direction, and the hanging mass plus

In this scenario, the tension was equal to the mass of the object plus the mass of the allotted amount of string. What kind of sources of error are found when doing a lab involving hanging mass and beams? A saw 7.
Log in or Sign up here!) Show Ignored Content Know someone interested in this topic? Why is more mass required to balance the meter stick as you move another mass farther from the pivot? The first source of error was the fishing wire we originally used to construct the mobile. get redirected here Mobile Project Objective: Our objective was to successfully build a themed mobile, at equilibrium, by making sure that the counterclockwise and clockwise torques are set equal to one another.

The only difference between the two experiments is that in the first, the spring is in constant equilibrium. AP Physics Lab Rubric You've already rated students with this rubric. d. Calculation errors which includes erroneous data entry in formulas 4.
This gave us more of a range to average our estimated periods. In the equation, "r" represents the distance of each object's lever arm, and "F" represents the force of each component of our mobile. If the awning is too heavy for the given supports, it may collapse and seriously injure those underneath it.
