Question

What is the IMA of the following pulley system?34567

Answer 1

Answer:

    IMA of given system =   $\frac{F_{r} }{F_{e} }$

Explanation:

• The "Ideal Mechanical advantage" (IMA) of given pulley is $\frac{F_{r} }{F_{e} }$ .

• 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 $F_{r}$. The input force is analogous or equivalent to the effort applied i.e. $F_{e}$ .

• Hence by dividing these two forces we calculate the IMA of the above mentioned pulley system which is  $\frac{F_{r} }{F_{e} }$ .
• Its mathematical reference would be:

                                                IMA =   $\frac{F_{r} }{F_{e} }$
