When a block is completely submerged under water, the buoyancy force on it is 11.6N; when it is completely submerged under an unknown liquid, the buoyancy force is measured to be 10.5N. What is the density (in unit of kg/m3) of the unknown liquid?
A rectangular metal block is 0.6 m long, 0.2 m wide, and 0.1 m tall. The block weighs 270 N. The block is lowered into an unknown fluid until it is completely submerged. In the fluid, the block weighs 164 N. What is the density of the fluid (in kg/m3)? Use g = 9.79 m/s2.
A cubic block of side lengths h and mass density p rests on a horizontal flat rigid plate, as shown. Assuming that the cube is isotropic and linearly elastic, whose material properties are characterized by the Young's modulus (E) and Poisson's ratio (v), determined the strain distribution in the cube due to the gravity field. For what value(s) of the Poisson's ration the cube will not change its lateral dimensions? gravity A cubic block of side lengths h and mass...
QUESTION 16 ifa fluid has a specific gravity of 8. then its density is equal to (kg/m3): QUESTION 17 A block of material of unknown volume is submerged in water and found to weigh 457 N (in water). The same block weighs 921 N in air. Determine the specific weight of the material in kN/m3. ou
