Question

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 level arm with length 97.8m causing a clockwise motion. What the torque?

Answer 1

The torque is 1799.52 N-m

Step-by-step 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.

`\tau =Fl\sin\theta`

Where, F = force

l = length

Put the value into the formula

`\tau =18.4*97.8\sin90^(\circ)`

`\tau =1799.52\ N-m`

Hence, The torque is 1799.52 N-m

Answer 2

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

Step-by-step 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
