Experiment 101
RESOLUTION OF FORCES
In this experiment, we determined the resultant and equilibrant of system of forces using the force table given and after gathering the data, we compared them with the different methods involved. The main material we used in this experiment is called force table. It has system of strings with varying tensions that act concurrently. It also has 4 pcs of super pulley with clamp and 4 pcs of mass hanger which weigh 5 grams each. There is a ring in the center of the force table that indicates if the forces are balance. We began the actual experiment by increasing differently the mass of each hanger using the slotted mass. Afterwards, we measured the angles of the strings by using trial and error in

We tried to fix our mistake and it was fine. We were able to fix our mistake and continue the experiment. We had fun in balancing the force table and computing for the resultant by using component method and polygon method. The experiment gave us a preparation on how to solve certain situation that may happen in our lives.
V. EVALUATION
1. Why is it important for the ring to be at the center? Since the mass hangers have equal masses, can you disregard them in the experiment? Why?
- It is important for the ring to be at the center because it indicates if the forces are balance or not. You can’t disregard the ring in the experiment because it will affect the resulting value if you will compute for the resultant of the force.
2. When a pull is applied on the ring and then released, why does it sometimes fail to return to the center?
- Sometimes the forces are close to equilibrium but are not exactly equal so a slight disturbance in the balance will cause significant effect.
3. What is the significance of the resultant of F1, F2, and F3 to the remaining force F4? What generalization can you make regarding their relationships?
- It will act as a force that will completely neutralize F4. The force F4 and the resultant of F1, F2, F3 are exactly opposite of each other.
4. If the order of adding vectors is changed (i.e. from F1 + F2 + F3 to F2 + F1 + F3) will the resultant be different? Why?
- No, because
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.
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
Assemble the ring and ring stand atop a flat surface. Place the clay triangle in the center of the ring. Lastly, bring the crucible with its lid into the clay triangle, so that it is hanging.
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
The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment, gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different
5. What’s really meant is that the forces are the same but going in different directions as a mirror image of one another. So when one force is going for example 2 newtons in a positive direction, the same amount is going in the opposite direction.
It does the same thing as the active force does except for in increases at the end again.
Place the ring stand in an area that allows up to a 150cm length of string for the pendulum to move without any obstructions.
The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of
In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.
HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction.
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.
Following tables and graphs show the result of the experiment. The tables will demonstrate the experimental and theoretical deflection for each case. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.
3) In this experiment, only the forces on the plane surface were considered. Do the hydrostatic forces on the curved surface of the quarter-circle block affect the measurement? State why or why
