An asteroid made out of iron (7860 kg/m3) strikes the Earth in an areawhere the oceans are very deep. The velocity of the asteroid upon impact isthe same for most debris hitting the Earth’s atmosphere, 30 km/s.The difference in potential energy from orbit to ground is negligible at thisspeed. Assuming that 80% of the asteroid’s kinetic energy is transferred toheating the water, what volume of water (assuming a density of 1000 kg/m3)will be vaporized? We will assume that the water is taken from 70o F tothe point that it becomes steam. Also, assume that the asteriod is spherical,with a radius of 750 m.
Fuel cell systems are regarded as a promising solution for future electrical energy generation onboard of commercial aircraft. The Hydrogen gas supplied to the fuel cell is normally stored athigh pressures or cryogenically. The following gas cylinder in figure Qu 7 is used and is to belocated in the cargo hold of the aircraft.Figure Qu 7The rigid container holds 0.9 kg of hydrogen gas initially at 15bar and 20oC. As the altitude of theaircraft increases and economical cruising speed is achieved the cargo temperature, and the cylindertemperature, drops to 0oC. Determine the final hydrogen pressure at the new altitude and heat lostduring the ascent.For Hydrogen, R = 4.126 kJ/kgK, cv = 10.16 kJ/kgK

The force required to compress the gas in a gas spring a distance x is given by F = Constant/xk where the constant is determined by the geometry of this device and k is determined by the gas used in the device. One such device has a constant of 200 lbf·in1.4 and k 5 1.4. Determine the work, in Btu, required to compress this device from 2 in to 7 in.
When a .22-caliber rifle is fired, the expanding gas from the burning gunpowder creates a pressure behind the bullet. This pressure causes the force that pushes the bullet through the barrel. Suppose the barrel has a length of 0.633 m and an opening whose radius is 2.67 x 10-3 m. A bullet (mass = 2.6 x 10-3 kg) has a speed of 348 m/s after passing through this barrel. Ignore friction and determine the average pressure of the expanding gas.

One end of a timber roof truss is supported on a brick wall but not securely fastened. The reaction of the brick wall can therefore be only vertical. Assuming that the maximum capacity of either the inclined or horizontal member is 7 kN, determine the maximum magnitudes of Fl and F2 so that their resultant is vertical through the brick wall.

A cylinder contains one liter of air at room temperature (300 K) and atmospheric pressure (105 N/m2). At one end of the cylinder is a massless piston, whose surface area is 0.01 m2 . Suppose that you push the piston in very suddenly, exerting a force of 2000 N. The piston moves only one millimeter, before it is stopped by an immovable barrier of some sort. How much work have you done on this system?
Battleships! In 1905, as part of the Russo-Japanese War, the Imperial Japanese Navy (IJN) under the command of Admiral Togo engaged the Russian fleet under the command of Admiral Rozhestvensky in the Battle of Tsushima. This was the first major naval engagement to be dominated by "big guns." In this question we will model the 12" Armstrong Whitworth guns employed by the IJN. The guns are capable of firing a 390kg shell at a speed of 732ms-1. For simplicity, we shall assume that this shell is a sphere of diameter D such that the drag due to air resistance can be approximated as 1 FD 2 CppAv²: = cv? 16 where Cp= 1/2 is the approximate drag coefficient for a sphere, A = T(D/2)2 is the reference area, p - 1.225kgm-3 is the density of air at sea level, and v is the velocity, whence C = 16PD? The overall force experienced by our shell in flight is hence F = mg - - cv³v , where m is the mass of the shell and g is the acceleration due to gravity, v= v and v^ = v/v, with v corresponding to the…
