# force table error analysis Perryman, Maryland

Avoid situations where all hangers have the same weight. If it is not, determine from your graph the magnitude of the deviation from zero. Record the uncertainty of the force and its percent uncertainty. BACKGROUND: Read the chapters on vectors and components of vectors in any physics textbook. 4.

We used a force table to determine how much weight and what degree the vectors would need to be in order to make the force equal to zero. In steps 6-7 of the prodecure, you will be asked to use the Graphical andAlgebraic methods first to predict the resultant for a set of three vectors. Draw the line of action of this vector along the edge of the triangle. Note that the error in the latter is obtained from the error in its tangent.

The size (magnitude) of a vector is always positive, and may be found by using the Pythagorean theorem if the components are known. Analytical Sum Calculate the resultant force on the ring, FT = F1 + F2 + F3, analytically for Equilibrium with Three Forces only.

In your own words, describe the situation to be studied.2. Please help if you can!!! The uncertainty in these angles should be limited to the precision to which you can read the angles on the force table. 4 Run two of the strings (attached to the Components of vectors by the analytic method.

Why not? Pleasesummarize your results into a table. The system returned: (22) Invalid argument The remote host or network may be down. Discussion Is the condition for static equilibrium, FT = 0, satisfied for both parts of the experiment?

It is not necessary to move the original vectors on the sheet. Do this, and find the full range of the uncertainty in each force. Record the amount of weight on each hanger, and read the direction of its string on the table's scale.

The force table apparatus demonstrates the addition of forces acting on a body, in two dimensions. E. The angle of a vector is conveniently specified with respect to the positive x axis, measured counterclockwise. Use 200 to 500 gram weights on the hangers.

I feel that the second most important factor would be the fact that we ignored the mass of the strings. If the components are known, the angle is arctan(Vy/Vx). In the case of static equilibrium, which you are investigating, the vectors will very likely add to nearly zero, so that any resultant A+B+C will be very small relative to the Your results section should include the resultant magnitude and directionfor all three methods for each of the three parts of the experiment.

APPARATUS: Force table, three weight hangers, metric weight set, 17 x 11 or 17 x 22" drawing paper. 3. When you achieve equilibrium of the body, the directions of the forces lie along the direction of the strings. Why is this important? Investigate and record the error in the angle in the same way. 7.

Friction is another force, and it too, has to balance out to create true equilibrium. The final factor regarding friction in the pulleys is still important. The uncertainty of these measurements should be limited to the precision of the balance. 3 Place the pin in the middle of the force table and place the ring over the Add weights to the weight holder until the ring pulls away from the pin, so that the pin is not necessary to hold the ring in place.
