MCQ
Find Mechanical advantage for pulling mass $M$ by the person
  • A
    $2$
  • $4$
  • C
    $8$
  • D
    $16$

Answer

Correct option: B.
$4$
b
$\mathrm{M.A.}=\frac{\mathrm{Load}}{\varepsilon \mathrm{ffort}}=\frac{\mathrm{Mg}}{\mathrm{T}}$

$\mathrm{Mg}=4 \mathrm{T}$

$\Rightarrow \mathrm{M.} \mathrm{A.}=4$
