Question

A force of $525N$ produces a moment of force of $420Nm$. Calculate the shortest distance between the point of application of force and the turning point.

• A. $2.8m$
• B. $0.8m$
• C. $1.8m$
• D. $0.4m$

Answer 1

The correct option is B $0.8m$

Force $F=525N$

Moment of force $\tau =420Nm$

Shortest distance between the point of application of force and turning point $r=\frac{\tau }{F}$

$⟹r=\frac{420}{525}=0.8m$
