What is the IMA of the following pulley system?

34567

    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 =
