Answer:
IMA of given system =
Explanation:
- The "Ideal Mechanical advantage" (IMA) of given pulley is
.
- Ideal Mechanical advantage of a system is defined by the ratio of achieved or output force to the implied force. In the pulley system above, output force is the resistant force denoted by
. The input force is analogous or equivalent to the effort applied i.e.
.
- Hence by dividing these two forces we calculate the IMA of the above mentioned pulley system which is
- Its mathematical reference would be:
IMA =
