The Theory Of The Second Pulley

Repeat this at the same setting 1 more time to find an average. At the same angle, choose a second setting of force and repeat the process. Follow this procedure using different angles.

By going through the force diagram2 of the system below, the number of components those are highly stressed and because of which may fail or lack in desired performance is four.

A. How did the experiment in Part I demonstrate surface tension? Use your experiment observations when answering this question.

To begin the experiment, we measured the masses of the two stoppers and the eye bolt used to secure the stoppers that we were using in our apparatus. The mass of the first stopper was 18.8 grams and the mass of the second stopper was 50.5 grams. The mass of the eye bolt was 11.6 grams. The mass of the screw and bolt that secured our hanging mass was given to us as 25 grams. After, we chose six different hanging masses based on stopper mass. We made sure that the hanging mass was always larger than the stopper mass or else we would not be able to get the stopper to spin at a constant velocity. The first three mass ratios we chose was using the stopper with the mass of 18.8 grams and then we used a hanging mass (the mass of the screw and bolt is included) of 65 grams, 85 grams, and 105 grams. This gave the three mass

After collecting data and analyzing the results the group concluded that tension will always be greater than mass for uniform constant motion due to the presence of θ. As the length of the string for the flying toy increased, θ decreased in both trials for the cow and bat. For instance, when the bat had a length of 0.86m, the calculated θ was 34.4°, but when the length was shortened to 0.61m, the θ increased to 36.5°. The period was also shortened when the length decreased; therefore, velocity decreased as string length increased while acceleration increased with a

Using Gravitational Force as a Measurement Tool Answer the following questions about the results of this activity. Record your answers in the boxes. Send your completed lab report to your instructor. Dont forget to save your lab report to your computer Activity 1 Record your data from Activity 1 in the boxes below. Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results. You will need to use the following formula to assist with your laboratory report G-force 0 00001118 x radius of centrifuge arm x (rpm)2 The radius of the centrifuge arm for this instrument is 10 cm. Speed 5000 rpm 10000 rpm 15000 rpm

First, we will set up the force table. The table comes in three separate pieces the base, stand and table once we connect and fasten all three parts we must use a circular level to make sure the table is balanced. If the force table isn’t balanced then we must adjust the base’s feet to the appropriate levels on each leg till the bubble on the level is centered. We must then assign where the positive & negative x, y axis are on the force table as a point of reference and label them with tape .Then for part I we must apply 1.96 N in the positive x – direction, and 2.94 N in the positive y-direction then we must balance the two with a third force and record the magnitude and direction of it and a draw a diagram showing all three forces. Part II

2. No, the forces went in equal and opposite directions just as the rubber band and string

Purpose/Question: Does adding paperclips to the whirlybird affect how long the object takes to reach the ground? Hypothesis: If an individual adds more paperclips to the whirlybird, then the speed the object takes to reach the ground will be faster because, the whirlybird will weigh more every time you add a paper clip making the force of gravity greater.

Use a protractor to measure 30° from the equilibrium. Release the pendulum at this angle.

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

5. The length of the lever arm for the clockwise moment has to be increased as more weights at the fixed distance to the left of the pivot increases. This is because when more weights are added, the anticlockwise moment increases. To achieve equilibrium, anticlockwise moment must equals to clockwise moment. So at the clockwise moment where the mass is constant, the length must be increased so that the clockwise torque produced can balance the anticlockwise torque.

Below are two tables in which I have recorded the data which I obtained during the experiment. The first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of the load and the second table reflects the relationship between the flexion of the cantilever and the length of the cantilever.

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.

The trifilar suspension was assembled and the lengths of the chains were measured, recording their average length. In order to repeat the experiment, applying the same amount of force each time, a tangential reference line was drawn on the circular platform and marked with a corresponding point on the table.
