A Decsription of Torque

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

A system is Material moving most stable when it has reached equilibrium. A out of the cell system will tend to go to equilibrium (lowest, accessible energy state) in the absence of added energy (Figure 2).

Locate the force string and use the hooked end to connect the force string to the other side of the spinning mass. Guide the force string over the pulley. Suspend the mass hanger plus an additional 0.55 kg of mass, so that m= 0.6 kg. Ensure that the weight hanger does not touch the table top. This hanging mass will be referred to as the force mass from now on, and is used to set the centripetal force, Fc. The force Fc is equal to the force mass, in kg, multiplied by gravity. Calculate this value and record it onto Data Sheet C. Adjust the tension knob so that the tip of the spinning mass is directly above the

I learned that mass and volume work together to find the

If a structure is in static equilibrium, then any portion or segment of it must also be in static equilibrium. With this

2. (TCO A) Which of the following best shows forces for change vs. forces for stability? (Points : 7)

To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.

If no torque is applied the momentum stays the same. The angular momentum is the rotational interia times the angular velocity. The greater the rotational interia the smaller angular velocity.

Dynamic Equilibrium: Two offsetting processes occur at equal rates, producing a state of balance where no net changes is observed.

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)

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.

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.

The beam was loaded the mid-length in 2.745 lbs. increments up to 6.745 lbs. The change in clearance of every load step was measured and data was recorded.

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.

Dans la deuxième expérience, le but est de mesurer les différentes forces agissant sur un objet au repos grâce à un instrument (le dynamomètre) en fonction de l’angle auquel est incliné le plan sur lequel l’objet est posé. Puis, on calculera la force combinée et on fera un
