write the application of simple machines
Answers
Answer:
The modern world is rich with examples of complex machines whose workings are seldom understood. Students (and many adults) commonly use the word ‘machine’ to describe complex mechanical devices powered by an engine or electric motor and designed to perform useful labour saving tasks.
Students often believe that all machines produce much more work than their human operators put in. This view is consistent with their experiences of most powered mechanical devices e.g. chainsaws, electric power tools and hydraulic excavators.
Students’ everyday experiences seldom acknowledge devices like levers, inclined planes, wedges and pulleys as being types of ‘simple machines’. Although most students will have common experiences of the use of simple machines like levers and pulleys, few will have any understanding of why their design may provide an advantage or how they should be best employed. Many students also have difficulty in identifying or explaining these experiences to others and rarely identify parts of the human body, such as the arms or legs, as composed of levers.
