Early Engineering Work
In 1902 Pearse built and patented a bicycle which was the first flight ever made with vertical crank gears and self-inflating tyres. He then designed and built a two-cylinder "oil engine" which he mounted on a tricycle undercarriage surmounted by a linen-covered bamboo wing structure and rudimentary controls. Although it lacked an aerofoil section wing, his flying machine resembled modern aircraft design much more than did the Wright brothers' machine: monoplane rather than biplane; tractor rather than pusher propeller; stabiliser and elevators at the back rather than the front; and ailerons rather than wing-warping for controlling banking. It bore a remarkable resemblance to modern microlight aircraft.

Famous quotes containing the words early, engineering and/or work:
“Mormon colonization south of this point in early times was characterized as “going over the Rim,” and in colloquial usage the same phrase came to connote violent death.”
—State of Utah, U.S. public relief program (1935-1943)
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
“To-day ... when material prosperity and well earned ease and luxury are assured facts from a national standpoint, woman’s work and woman’s influence are needed as never before; needed to bring a heart power into this money getting, dollar-worshipping civilization; needed to bring a moral force into the utilitarian motives and interests of the time; needed to stand for God and Home and Native Land versus gain and greed and grasping selfishness.”
—Anna Julia Cooper (1859–1964)
