Answer to Question #133864 in Classical Mechanics for alfraid

Question

a force 2N is applied from a point O to perpendicular distance 4m.find the torque due to this force.

Answer 1

SOLUTION

given data

force applied(F)=2N

perpendicular distance(d)=4m

torque can be given as

$\tau=Fdsin\theta$

force is perpendicular to distance so angle wiil be $\frac{\pi}{2}rad$

$\tau=2\times4sin\frac{\pi}{2}$

$\tau=8Nm$
