Experimental Procedure 1. Setup ring stand with five inch ring and triangle. 2. Obtain desired amount of Magnesium‚ a crucible with a lid and crucible tongs. 3. Weigh the crucible‚ crucible lid and the obtained magnesium and record respective weights. 4. Heat the crucible with the magnesium in it and place the lid so that there is a small opening. 5. Continue to heat at medium heat for five minutes. 6. Then‚ heat at high heat for five minutes. 7. Shut burner down and let the magnesium

burdens outweigh the physical agony that those in war must carry: "They carried all the emotional baggage of men who might die. Grief‚ terror‚ love‚ longing--these were intangibles‚ but the intangibles had their own mass and specific gravity‚ they had tangible weight". O’Brien argues that fear‚ longing‚ responsibility‚ and uncertainty that the soldiers experience far outweigh the physical torture that they must endure in order to stay alive‚ burdens that are lightened only a little by the hope of returning home

from the point to the line of action of the force. This can also be written as Tcm=Tccm. Equipment: Ruler Weights A metal poll Hangers Procedure: The first thing we did to start this lab was to set up the experiment and find the equilibrium point. This can be bit tricky because you have to be sure that everything is equal and it not being tilled. Once this is done you will add weight and measure the point from the origin to see what the distance was to

Purpose. The purpose of this lab was to understand equilibrium. To do this‚ you must find the equilibrant of the resultant of three vectors‚ both mathematically and graphically and test the results. Procedure: A) Put the weights necessary for each of the vector forces on each hook. B) Set the wheels of the force table at the proper angles‚ including the calculated equilibrant. C) When placing the hooks on the wheels‚ be careful to hold the table in place so it does not flip over. D) To test

Erroneous statements about the weight of Medieval and Renaissance swords are unfortunately common. It is an issue of the most habitual misinformation and misstatement. This should come as no surprise given the misrepresentation Medieval and Renaissance swordplay continually receives in popular media. Everywhere from television and movies to video games‚ historical European swords have been depicted as being cumbersome and displayed with wide‚ exaggerated movements. On a recent national television

different food items using the change in water temperatures from the heat of the food. Procedure: 1. With your digital scale determine the empty weight of your 100-mL beaker. 2. Half-fill the beaker with water (approximately 50 ml) and weigh it again. 3. The beaker and water weight minus the empty beaker weight is the net weight of water used for this experiment. Record it. 106.7-65.9=40.8g 4. Place aluminum foil on the table top to catch any spills and also to reflect heat upward

Experiment #4 Torque ABSTRACT The objective of the experiment is to observe how the weight of the beam on which the forces act behaves like a force concentrated at the center of gravity of the beam and to determine the conditions of equilibrium for several parallel forces. Before the experiment proper‚ Torque was discussed extensively. The experiment is divided into two parts. In the first experiment‚ the meter stick was weighed and the group was tasked to find the center of gravity of

PAPER BRIDGE COMPETITION (GROUP PROJECT) OBJECTIVES: To construct a free span paper bridge that is capable of supporting a number of weights. The best score is achieved by total weight supported. SPESIFICATIONS: The bridge must be constructed from only paper and tape. Standard 4 pieces A4 paper size up to 80 GSM only can be used. The bridge span must be the A4 paper width. Glue can be used to join the members; for example‚ along the seam of a tubular member or at a point where two or
