A square steel plate is 8.00 cm on a side and 0.300 cm thick. Assume that the plate is oriented with the square faces horizontal to the ground. a force of magnitude 7.00×105 N is applied to both the top and bottom surfaces of the plate (the square sides). Each of the forces is applied in a direction parallel to the surface they are exerted on, and they point in opposite directions. Find the shear strain caused by these forces....

A stainless-steel-bottomed kettle, its bottom 28 cm in diameter and 1.6 mm thick, sits on a burner. The kettle holds boiling water, and energy flows into the water from the kettle bottom at 800 W . What is the temperature of the bottom surface of the kettle? Thermal conductivity of stainless steel is 14 W/(m⋅K). Express your answer in degrees Celsius to four significant figures.

A 1,200Kg boat is sunk in the harbor and sits on the bottom a depth of 30m. A plan to raise the boat using ping pong balls has been put in place. The boat is sealed so that the ping pong balls can be added to the boat and will remain in the boat displacing enough water to raise it to the surface. An average ping pong ball is 4 cm in diameter. (a) Assume that all of the ping...

Steel has a density of 8.0 g/cm3. Let's plan building a spherical shell, made out of 2.0 cm thick steel. The perfectly spherical shell will have outer diameter of 2.0m. You can think of such a shell as a solid sphere, and then you cut out a sphere that has a 2.0cm smaller radius. 2. How heavy is that hollow sphere? Would this sphere float in water? a. b.

Many small sailboats use a passive bailing system: there is a plug in the bottom of the boat that can be opened to drain water out of the boat. This works only when the boat is moving, because only then is the pressure under the boat less than air pressure, by Bernoulli’s equation. Consider a boat whose bailing plug is located 3 cm below the surface of the water. What is the minimum speed the boat must have so all...
