Free body and kinetic diagrams of an inclined block. In dynamics a kinetic diagram is a pictorial device used in analyzing mechanics problems when there is determined to be a net force and/or moment acting on a body. They are related to and often used with free body diagrams, but depict only the net force and moment rather than all of the ...
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. [1] [2] [3] The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move ...
It has a mechanical advantage (MA) = 1 (assuming frictionless bearings in the pulley), moving no mechanical advantage (or disadvantage) however advantageous the change in direction may be. A single movable pulley has an MA of 2 (assuming frictionless bearings in the pulley). Consider a pulley attached to a weight being lifted.
Originally steam powered, the Duquesne Incline was designed by Samuel Diescher, a Hungarian-American civil engineer based in Pittsburgh, and completed in 1877.The incline is 800 feet (244 m) long, 400 feet (122 m) in height, and is inclined at a 30-degree angle.
Dubbed the "World's Steepest Vehicular Inclined Plane", it is 896.5 ft (273.3 m) long, and ascends 502.2 ft (153.1 m) from the city valley to Westmont hilltop at a 70.9 percent grade. The São Paulo Railway in Brazil employed a series of five inclines to connect the port city of Santos to Rio Grande da Serra , rising 2,625 ft (800 m) in seven ...
Samuel Diescher (June 25, 1839 – December 24, 1915) was a prominent Hungarian-American civil and mechanical engineer who had his career in the United States. After being educated at universities in Karlsruhe and Zurich in Europe, he immigrated to the United States in 1866 and settled in Cincinnati, Ohio.
The Johnstown Inclined Plane was designed by Hungarian-American engineer Samuel Diescher, who had also designed the Duquesne, Castle Shannon and Fort Pitt Inclines in Pittsburgh. [4] The funicular consists of a parallel set of 8 ft ( 2,440 mm ) broad gauge railroad tracks with a 70.9% grade or an angle of 35 degrees and 28 minutes from the ...
Engineering is the practice of using natural science, mathematics, and the engineering design process [1] to solve technical problems, increase efficiency and productivity, and improve systems. Modern engineering comprises many subfields which include designing and improving infrastructure , machinery , vehicles , electronics , materials , and ...
