Question

A force of F in applied to a wrench at a 0 degree angle to the handle. Theforce is applied - meters from the pivot point. Calculate the torques.

Answer 1

The torque (tendency of an object to rotate) depends on three different factors:

$\tau=Fr\sin\theta$

r - the distance between the pivot point and the point of force application

F is the force

θ is the force

a)

$\begin{gathered} \tau=80*0.2*\sin60 \\ \tau=13.85\text{ Nm} \end{gathered}$

b)

$\begin{gathered} \tau=40*0.4*\sin60 \\ \tau=13.85\text{ Nm} \end{gathered}$

c)

$\begin{gathered} \tau=40*0.4*\sin30 \\ \tau=8\text{ Nm} \end{gathered}$
