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).

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

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

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

Place the ring stand in an area that allows up to a 150cm length of string for the pendulum to move without any obstructions.

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

When the environment is in equilibrium, it has a minimum potential energy (mgz) and a zero speed (v=0), so kinetic and potential energy changes are omitted and it reduced to Eq. 3.

For this method the ring should be centered over the post when the system is in equilibrium. So we tack the center post down so it will flush with the top surface of the force table and it will be no longer comptent to hold the ring in the position. We also pulled the ring slightly to the one side and release it to enable to inspect that the ring returns to the center. Then if not, adjust the mass or/and the angle of the pulley until the ring constantly returns to the center when it is pulled slightly to one side.

Start by pulling down the middle of the bar of the hanger, creating a square

In order to calculate frequency, the free body diagram must be taken into consideration in order to calculate the force of tension. In this lab, the force of tension and gravity are assumed to be the only forces. Furthermore, the

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.

A pulley was attached to the end of a lab table. The total length of the string used in the experiment was measured before the first knot and weighed by a lab balance. The linear mass density was calculated using the following equation: µ= m/Lo. Then, the pre-measured string was tied to a string vibrator and a mass hanger (hanging from the pulley by the string) with the pulley parallel to the surface of the table. The length of the string that was able to undergo vibrations was measured by a meter stick. Next, the vibrator was turned on and a variety of standing–wave patterns were produced by gently pulling down on the mass hanger. All results were recorded.

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

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.
