Calculate the torque and be sure to include units and sign.

A force of 18.4 N is applied perpendicular to the end of a long lever arm with a length of 97.8 m, causing a clockwise motion. What is the torque?

Answer :

Answer:

Torque = -1799.52 Nm or 1799.52 Nm (clockwise direction)

Explanation:

Torque = Force x Perpendicular distance

Here force is given as 18.4 N and Perpendicular distance = 97.8 m

Substituting

Torque = Force x Perpendicular distance = 18.4 x 97.8 = 1799.52 Nm

Torque = 1799.52 Nm (clockwise direction)

Usually anticlockwise is positive

So torque = -1799.52 Nm

Answer:

The torque is 1799.52 N-m

Explanation:

Given that,

Force = 18.4 N

Length = 97.8 m

We calculate the torque,

Torque is the product of the force and perpendicular distance.

[tex]\tau =Fl\sin\theta[/tex]

Where, F = force

l = length

Put the value into the formula

[tex]\tau =18.4\times97.8\sin90^{\circ}[/tex]

[tex]\tau =1799.52\ N-m[/tex]

Hence, The torque is 1799.52 N-m
