Given:-

☛Efforts = 8kgf

☛Loads = 100kgf

☛Distance through efforts = 50cm

☛Distance through loads = 3cm

 

Find:-

☛a)velocity ratio

☛b) mechanical advantage

☛c)percentage efficiency of the machine

   

Solution:-

☛a) velocity ratio-

\sf{Velocity \ radio = \dfrac{d_e}{d_l} }

where, d_e = Distance through effort moves

d_l= distance through load moves

\sf{\implies V.R. = \dfrac{50}{3}  }

velocity ratio = 50:3

☛b) Mechanical advantage-

\sf{M_{advantage} = \dfrac{load}{efforts} }

\sf{M_{advantage} = \dfrac{100}{8}= 12.5 }

Mechanical advantage= 12.5

☛c)Percentage efficiency of the machine-

\sf{ it \ is \ given \ by \rightarrow}

\sf{ \%  = \dfrac {Mechanical \ advantage}{Velocity \ ratio} \times 100}

\sf{ \implies \dfrac{12.5}{\dfrac{50}{3}} \times 100}

\sf{\implies \dfrac{12.5}{16.66} \times 100}

\sf{\implies 75.03}

Percentage efficiency of the machine is 75.03%
