Ajet transport with a landing speed of 300 km/hr reduces its speed to 65 km/hr with a negative thrust r from its jet thrust reversers in a distance of 440 m along the runway with constant deceleration. the total mass of the aircraft is 140 mg with mass center at g. compute the reaction n under the nose wheel b toward the end of the braking interval and prior to the application of mechanical braking. at the lower speed, aerodynamic forces on the aircraft are small and may be neglected.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
