Dear 10.2W,
Welcome to your second e-lesson! I know it’s a day early but I’m probably going to be without internet tomorrow…
This e-lesson consists of 3 objectives; 1.23, 1.25 and 1.26.
Instructions for Objective 1.23
1. 1.23. Learn the formula and units. Have a go at the quick questions (the five animations attached)
2. 1.23 Moments Questions. Forward this e-mail to your blog. Type your answers under the questions.
3. Answers to step 2 will be sent separately. Don’t look at them until you’ve done the work!

· 1.23 recall and use the relationship between the moment of a force and its distance from the pivot:
moment = force × perpendicular distance from the pivot
· A moment is a turning force
· It depends on the size of the force and the perpendicular distance from the pivot
M = F x d
M = moment (Nm)
F = force (N)
d = perpendicular distance from the pivot (m)
Worked example
M = F x d
M = 1 x 5
M = 5Nm
Quick questions.
(No need to type anything - just open the animation, choose your answer and then check your answer)
