Use enough weight on the hangers so the strings are nearly parallel to the table and do not sag much. Example: Refer to Fig. 6. Measure the sizes of the components and record these in tabular form. Please try the request again.

Cristy · 7 months ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse Add your answer Errors that can occur during a force Read the magnitude and direction of the resultant from your graphical solution and record them in Table 2. The size of this error is estimated by determining how much the weight on a weight hanger can be varied without disturbing the equilibrium. Strings attach to a ring at the center, pass over the pulleys to weight hangers.

The sum of the vectors representing the forces is zero. (2) The sum of the components of force along any axis is zero. 6. Set up an equilibrium situation with three forces acting on the ring. Estimate how much additional error is introduced into the drawing by construction and measurement steps. Simanek.

In each situation, adjust the weights and angles so that the ring is centered on the table, and is not touching the center post.

Without this uniformity, the whole experiment would have turned up different numbers due to error.

Calculate the magnitude of the forces produced by these masses and record them in Table 1.

Merely drop construction lines (dotted lines in Fig. 5) from their heads and tails, perpendicular to the chosen axis. Answer Questions A ball of mass 200 g is released from rest at a height of 2.40 m above the floor and it rebounds straight up to a height of 0.950 Generated Sat, 15 Oct 2016 23:28:32 GMT by s_ac15 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.9/ Connection Expand» Details Details Existing questions More Tell us some more Upload in Progress Upload failed.

Good bookkeeping. For example, the following table keeps track of the numbers of exercise 1. Fig. 1. The vectors may be assembled into the polygon in any order, since vector addition is commutative.

In fact, there are an unlimited number of other starting points on the surface of the earth from which this may be done, and they all have a special relation to illustrates the addition of three vectors by the polygon method. Then, we measured the angle of the resultant. Â (See Appendix) Finally, we calculated the percentage error of the magnitude of the experimental value of FR compared to the analytical solution of The magnitude of the string tension (force) is determined by the amount of mass that is hung from the other end of the string.

Fig. 3. It probably won't close perfectly. Please help if you can!!! The angle of a vector is conveniently specified with respect to the positive x axis, measured counterclockwise.

Urwin Are you sure?This action might not be possible to undo. The magnitude (strength) of each pull and its direction can be varied. PURPOSE: (1) Study static equilibrium under the action of several concurrentforces. (2) Test whether the forces on a body at rest add to zero. (3) Study how errors in vectors propagate. a) in how much time did the ball reach maximum height?

Why?I think that they would. For each situation, choose arbitrary X and Y axes, and resolve the vectors into components along these axes. You can only upload a photo or a video. Your cache administrator is webmaster.

Using equation 1, calculate the components of F1 and F2 and record them into the analytical solution portion of Table 3. This last question will require considerable analysis, and a consideration of how to do an error propagation calculation for vectors.

Record the amount of weight on each hanger, and read the direction of its string on the table's scale. KaneDover Books on Physicsby H.C. Yes No Sorry, something has gone wrong. Important:The force exerted by a string on the ring is the sum of the weight on the hanger plus the weight of the hanger.

When a body is in static equilibrium: (1) The vector polygon of all forces acting on the body in static equilibrium is closed. Add the components algebraically and determine the magnitude of the resultant by the Pythagorean Theorem. The hanger's mass is usually marked on the hanger, but it's a good idea to check that by weighting them yourself. Is its size consistent with the error caused by error in each of the individual forces?

Why is this important? The post can then be removed. What would the total electrical charge of a baryon composed of only up quarks? Please upload a file larger than 100x100 pixels We are experiencing some problems, please try again.

We found the equilibrium minus the mass of the strings which could have led to some error, especially if the strings were different and, therefore, had a different mass value. Components of vectors by the analytic method.

Round-off or arithmetic errors in our calculations could also account for the different results. b) what is the maximum height? Please try the request again.
