Fuller, Robert W. (Robert Warren), 1871-1953, Brownlee, Raymond B. (Raymond Bedell), b. 1877 joint author, Carhart, Henry Smith, 1844- First principles of physics. [from old catalog] · Boston, Allyn and Bacon · leaf 109
over a fulcrum in order to find lrThe loading may be done by attaching a strip of brass, iron, orlead to one end of the half meter stick, at right angles to the stick. 94 LABORATORY EXERCISES the center of gravity (Fig. 37, A). Then a 200-gramweight will be hung about 10 cm. from the free end of… … Fig. 37. This moment equals the moment of the force at the centerof gravity about the fulcrum. Then the force at thecenter of gravity is calculated. A second trial should be made with the weight at someother point on the stick, as 20 cm. from the end. Finally the loaded stick is weighed. All…
