The motion is a rapid pitching of the aircraft about the center of gravity, essentially an angle-of-attack variation. The short-period mode is an oscillation with a period of only a few seconds that is usually heavily damped by the existence of lifting surfaces far from the aircraft’s center of gravity, such as a horizontal tail or canard.
Union cries foul. TORONTO (AP) — Freight trains in Canada could be running again within days after the government forced the country’s two major railroads into arbitration with their labor ...
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture . Theoretically, the stress ahead of a sharp ...
The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. [ 1] Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft.
Benjamin Harrison served as the 23rd President of the United States. He defeated incumbent Grover Cleveland in 1888, but lost to the Democrat in 1892.
But Betts missed 1 1/2 months with a broken left hand and the Dodgers weren't quite the same in his absence. That gave the D-backs and Padres the opening they need to make a move.
ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard [ 1] published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO (the ...
