An inclined plane is a flat supporting surface tilted at an angle‚ with one end higher than the other‚ used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck‚ to a person walking up a pedestrian ramp‚ to an automobile or railroad train climbing a grade. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks‚ ships‚ and planes. Wheelchair

Sam Preusser Mr. Staude U.S. History 25 April 2013 Truman Doctrine VS. Marshall Plan The years after the war brought times of disagreement and argument. The United States worked at this time to contain and control the spread of communism. During the years of WWII and the Cold War this idea was prominent and an issue America thought must be solved. Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making

Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated

TUBERCULOSIS Tuberculosis‚ commonly known as TB‚ is a contagious and an often severe airborne disease caused by a bacterial infection. TB typically affects the lungs‚ but it also may affect any other organ of the body. It is usually treated with a regimen of drugs taken for 6 months to 2 years‚ depending on the type of infection Tuberculosis was popularly known as consumption for a long time. Scientists know it as an infection caused by M. tuberculosis. In 1882‚ the microbiologist Robert Koch discovered

Bonnie Inman. In 1977 she was 21 years old‚ the same age that I am today. Therefore‚ this the year of discussion. This year saw several advancements in technology‚ and brought forth visions of the future of this field. On June 11‚ 1977 the first Apple II computers went on sale‚ which became the world’s first most popular personal computer ("News and Events of 1977."). Furthermore‚ on August 12‚ 1977‚ NASA made its first space shuttle test flight with the Enterprise ("News and Events of 1977."). These examples
