Question

Calculate the force that produces a moment of force of $2100dynecm$, when the perpendicular distance between point of application of force and turning point is $60cm$

• A. $65dyne$
• B. $35dyne$
• C. $70dyne$
• D. $85dyne$

Answer 1

The correct option is B $35dyne$

Torque $2100dynecm$

Perpendicular distance $r=60cm$

Force $F=\frac{\tau }{r}=\frac{2100}{60}=35dyne$
