Question

7.There is no gain in mechanical advantage in a single fixed pulley. En

why the pulley is then used.

Answer 1

The answer to this question can be defined as follows:

Step-by-step explanation:

Advantage:

• The load can be raised with one fixed pulley by adjusting the shifting pressure path.
• Its a fixed input pulley doesn't even have a mechanical advantage, the movement is larger than for the load.
• It is preferable to use because the pulley must not be moved up or down.
• It gains the measurement of just an increase in output power-to-input force ratio.
