Module 3 - Section 2 - Forces and Equilibrium

Question 1

What does resolving a force mean ?

Answer 1

It means splitting it up into components

Question 2

What should the arrow labels show when your drawing forces ?

Answer 2

They should show the magnitude and direction of the forces as a force is a vector quantity

Question 3

How do you resolve a force e.g. force, F

Answer 3

You would have to resolve the force into a horizontal and vertical component and they would be acting at right angles to each other - the forces would be called Fh and Fv

Question 4

What does coplanar mean ?

Answer 4

Coplanar means that they all act in the same plane

Question 5

How could you use a scale drawing to show that three coplanar forces are producing no net force ?

Answer 5

You draw the forces in a triangle with f2 after f1 and f3 after f2
then write that f1 + f2 + f3 = 0
