you read about a rope and pulley machine that was able to produce equal amounts of output work and input work.was this a realistic example? why or why not?

Respuesta :

nope.
It is non realistic example it is the ideal one (reversible machine).
Because you have friction loss and heat which would decrease the output work.

Answer:

No, it isn’t a realistic example.

Explanation:

This is an example of an ideal scenarios when we ignore frictional losses. But, in real life there are frictional losses and tension on the both sides of the pulley will be different. So, we cannot get output work is equal to input work. Hence, it is not a realistic example but ideal one.
