Page 53 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.

Page 16 - ... the sum of all the forces acting in one direction on the lever is equal to the sum of all the forces acting in the opposite direction.

Page 65 - Energy = —-{-« *g where V is the mean velocity, g is the acceleration due to gravity, and d is the depth of water. When the velocity of the water approaches the velocity of the elementary wave, the total energy of flow becomes unstable and variations in the profile of the free water surface will result. If the change in velocity is rapid a standing wave will form. 4 6 8 10 12 14 16 Specific En«rg...

Determine the volume of the specimen by measuring the volume of water displaced or by determining the weight of the water displaced. The weight in grams is numerically equal to the volume in cubic centimeters. 10.2. 1 Mode I — Place the specimen in a tank of known volume and add sufficient water to fill the tank. Then remove the specimen...
