A door handle is used to open a door - Leaving Cert Physics - Question b - 2017

To calculate the moment of the force, we use the formula:

$M = F imes d$

Where:

• $M$ is the moment,
• $F$ is the force applied, and
• $d$ is the distance from the pivot point.

Given:

• Force ($F$) = 40 N
• Distance ($d$) = 0.12 m

Substituting the values into the formula:

$M = 40 imes 0.12$

Calculating:

$M = 4.8 ext{ Nm}$

Thus, the moment of the force applied is 4.8 Nm.
