Conditions for symmetry ExperimentLaboratory ReportTricia Desierto, Luis Diaz, Karhen Estella, Gabrielle Beatrix Francisco section of Biological ScienceCollege of Science, University of Santo TomasEs scrapa, Manila, PhilippinesAbstractThe rejective lens is said to be in a resign of equilibrium, when the personnel offices performing upon an object are balanced. There were quad activities d unmatchable in the experiment. In the runner performance the equilibrant force out was getd. The twinkling activity, unknown forces was destined. For the third activity, nub of staidness was located. The last activity, rotational equilibrium was demonst prescribed.I. submissionEquilibrium is moving with continuous velocity. It is a condition that the rotational con summarizemation of the body may also remain constant. A body is in equilibrium or at rest only when there is no movement or rotation done. When the resultant force acting on the object is zero the object is in equilibrium. The objectives of the experiment are to determine the equilibrant force by use the character and table modeto determine the unknown forces using the first and irregular conditions for equilibrium to locate the inwardness of gravity of a composite bodyand to demonstrate the rotational equilibrium.II. surmisalA situation wherein the net force acting on a indisputable object is zero1 and an object that has no motion or undergoes no rotational and traditional accelerationis said to be in a state of equilibrium wherein net torque and net force on the object is zero in all directions. For an object to be in equilibrium, 2 conditions should be met.The first condition tells us that the net force acting on the object needs to be zero which only nitty-gritty that for a certain axis of motion, the forces acting along that particular axis should sum up to zero.2The second condition needed to attain equilibrium, on the other hand, involves avoiding or neglecting accelerated rotation an d it should maintain a constantangular velocity. A rotating body merchantman attain equilibrium if the rate of its rotation remains unchanged by the forces acting on that certain object.3The middle of gravity is a geometric property of any object. It is the intermediate location of the tiltof an object. Themotionof any object can be described through space in terms of the translation of the center of gravity of the object from one place to another and the rotation of the object about its center of gravity when it is free to rotate.4Figure 1.

The pivotal axis can be any point outside or inside the object. The objects elongated and angular accelerations are both zero and the sum of the torquesacting on a system should be equal to zero.T he sum of the counter-clockwise torques should be equal to the sum of the clockwise torques.5III. MethodologyActivity 1 Equilibrant ForceThree pans denominate as A, B and C was weighed. Pans A and B were hanged respectively at the 300 and 2000 marks on the force table. 100g was placed on pan A and 150g on pan B. The tension acting on the st camp, the pitch of the pan prescribed the weight added to the pan was recorded as TA andTB respectively. The two tensions in the strings were balanced by placing weight on pan C or adjusting its stick. The tensions are balanced if the pin is scarcely at the center of the ring. The magnitude of the equilibrant, the weight of pan C plus the weight added to it, and its position was recorded. The theoretical equilibrant of the two tensions was determined by component method and the % error was computed.Activity 2 First Condition for EquilibriumA piston chamber of unknown weight was suspended using the force board by means of two strings. A inau guration measure was attached to one of the strings and was pulled horizontally until the pin on the force board was exactly at the middle of the ring. The reading on the spring scale was recorded as T1. The angle that the other string do was recorded as . A free body plat of the ring was drawn. The tension of T2 in the other string and the weight of the cylinder were solved. The cylinder was weighed for the accepted value and the % error was computed.Activity 3 Locating the Center of GravityA circle with a diameter of 10cm and a square toes with a side of 10cm were cut out from a card board. The weights of WC and WS were determined. The center of gravity of the composite figure was determined by balancing method and plumb line method. The position of the center of gravity was specified using the leftmost side of the square as the y-axis and the bottom square as the x-axis. The results were checked by actual computation for the center of gravity.Activity 4 Second Condition for Eq uilibriumThe center of gravity of an aluminium forfend was located by balancing it on a pencil and the position for the center of gravity was marked. The cylinder utilize in the previous activity was hanged 5.0cm from one end of the pub. Using the force board, the aluminium bar was back up by means of a spring scale on one end and a string on the other end until the bar assumed a horizontal position. A free body diagram of the bar was drawn. The second condition for equilibrium was used to determine the weight of the bar and the tension in the string. The theoretical weight of the cylinder was used in the computation. The bar was weighed for the accepted value and the % error was computedIV. Results and DiscussionV. shutdownThe equilibriant force was successfully determined using the component and table method, with an pleasurable value for the % error 8.70% and 4.47%.The unknown forces were also determined using the first condition of equilibrium with a % error of only 4.57% The center of gravity was defined more accurately with the Plumb Line Method as opposed to the Balancing Method.The unknown forces were unsuccessfully defined using the second condition of equilibrium, as the % error exceeds the acceptable range at 51.76%.VI.
