Question 1.
Find the moment when a 10 N force is applied at a distance of 5 m from the pivot.
Show hintHide hint
Use the formula M = F × d.
Question 2.
What is the moment produced by a 25 N force at a distance of 2 m?
Show hintHide hint
M = F × d
3Question 3.
What is the formula for calculating moments?
- M = F × d
- M = F / d
- M = F + d

- True
- False
Show hintHide hint
Think about the moment arm.
Question 5.
A lever has a 12 N force acting at 1 m and an unknown force acting at 3 m. Solve for the unknown force.
Show hintHide hint
Use the principle of moments.
Question 6.
A 25 N force is applied at a distance of 2 m on one side of a pivot and 15 N at 1 m on the other side. Calculate where the pivot needs to be.
