Question

Since you used a ramp you only had to push with a force of 50 N in order to raise 125 N box. What is the mechanical advantage of this ramp?

Answer 1

• Input force=50N
• Output force=125N

$\\ \tt\hookrightarrow Mechanical\:advantage$

$\\ \tt\hookrightarrow \dfrac{Output}{Input}$

$\\ \tt\hookrightarrow \dfrac{125}{50}$

$\\ \tt\hookrightarrow 2.5$
