Arsenal played their third and final game of the 10-day USA tour against Premier League side Liverpool at Lincoln Financial Field in Philadelphia on 31 July. Goals from Mohamed Salah and Fábio Carvalho gave Liverpool a 2–0 lead. The Gunners pulled one back through Havertz's close-range shot, but they were unable to find an equaliser.
The Lanchester-Prandtl lifting-line theory [1] is a mathematical model in aerodynamics that predicts lift distribution over a three-dimensional wing from the wing's geometry. [2] The theory was expressed independently [ 3 ] by Frederick W. Lanchester in 1907, [ 4 ] and by Ludwig Prandtl in 1918–1919 [ 5 ] after working with Albert Betz and ...
In addition, the angle of the shock waves varies greatly with speed, making it even more difficult to design a craft that gains significant lift over a wide range of speeds. Higher speed designs using compression lift, waveriders, remain an interesting possibility for hypersonic vehicle designs, although only testbed models have been flown. [1]
Original script [2] Basic translation from Japanese [3] English version of the game [4] [a] 機関士： 何者 （ なにもの ） かによって、 爆発物 （ ばくはつぶつ ） が 仕掛 （ しか ） けられたようです。 Engineer: It appears someone has planted explosives. Mechanic: Somebody set up us the bomb.
The lifting power in air of hydrogen and helium can be calculated using the theory of buoyancy. The buoyancy depends upon the difference of the densities (ρ air) − (ρ gas) rather than upon their ratios. The lifting force for a volume of gas is given by the equation: F B = (ρ air - ρ gas) × g × V
Major General Vaughn Ary, Staff Judge Advocate to the Commandant displays lifting 30 lb ammo can 100 times during combat fitness test on December 4, 2011. This test was implemented in mid-2008 by Commandant of the Marine Corps James T. Conway as a more combat oriented version of, but supplement to, the Physical Fitness Test.
