Question

For a mechanism shown below, the mechanical advantage for the given configuration is

• A. 0
• B. 0.5
• C. 1.0
• D. $\infty$

Answer 1

The correct option is D $\infty$

Mechanical advantage
$=\frac{T_{\text{output}}}{T_{\text{input}}}=\frac{{\omega }_{\text{input}}}{{\omega }_{\text{output}}}\times \eta$

Since output link is a slider
${\omega }_{\text{output}}=0$

$\therefore \text{Mechanical advantage}=\infty$
