What is a Machine in Physics
Define Machine in Physics
A machine is a device by means of which useful work can be performed conveniently and it can also transfer one form of energy into another form of energy.
Mechanical Advantage:
The ratio between the resistance or weight to the power applied in a machine is called the mechanical advantage of that machine. It is denoted by MA.
- = Weight over-come by Machine/ Force Applied on the Machine
Efficiency:
The ratio between the useful work done and the work done on the machine is called efficiency.
MA = (output/Input) * 100
Input:
Input is the work done on the machine.
Output:
Output is useful work clone by the machine.
Note: Today, active processes of so-called “internationalization” are observed in the labor market. Our compatriots are increasingly finding work abroad, while our own companies are looking for “brains” in foreign countries. Migration of labor is more active, so if you are planning to get a higher education, it is worthwhile to think about where to do it. Currently, there are almost no cordons, many foreign universities offer a lot of specialized training programs for students from other countries. After graduating from a higher educational institution in a particular country, you can count on employment and citizenship. Future students are increasingly choosing to study abroad, and begin to prepare in advance for admission. In Canada, New Zealand , Australia, hundreds of thousands of foreign students from all over the world study. Let’s figure out what benefits a person who has enrolled in a foreign university gets. In general, higher education institutions have the opportunity to differentiate programs, modify them, adapt to modern realities. They do not study what they taught twenty years ago, but they keep pace with the times. All the knowledge gained to the graduate will be useful in future work.
