Question

a rider weighs 100N and is 0.5m away from the pivot. calculate the moment of the rider from the pivot. Give the unit

Answer 1

Answer:

what is intensity of sound?

Answer 2

Answer:

the moment of the rider from the pivot is 50 Nm.

Explanation:

Given,

Weight of the rider (W) = 100 N

The distance from the pivot (r) = 0.5 m

To find,

The moment of rider from the pivot (T)

Calculation,

We know that the moment from the pivot is nothing but the Torque

And Torque $(\bar{T}) = \bar{r} \times \bar{F}$.

Here force (F) exerted by the rider is the weight of the rider i.e. F = W = 100 N.

So, T = 0.5 × 100 Nm

 ⇒ T = 50 Nm

Therefore, the moment of the rider from the pivot is 50 Nm.

Nm is the unit of torque.
