Resolving Forces: Splitting a Single Force into Perpendicular Components

The video tutorial explains how to resolve a single force into two perpendicular components, using examples like a kite surfer and a box on an inclined plane. It demonstrates the use of scale drawing to calculate force components and discusses the concept of equilibrium in forces.

What is the purpose of resolving a single force into two perpendicular components?

• To simplify calculations

• To increase the force

• To change the direction of the force

• To reduce the force

In the example of the box on an inclined plane, what does the component parallel to the slope do?

• Pushes the box up the slope

• Pulls the box down the slope

• Balances the box

• Keeps the box in contact with the slope

What is the first step in creating a scale drawing to resolve a force?

• Draw the components

• Draw the force vector

• Choose a scale

• Measure the angle

How long should the arrow be for a 50 Newton force using a scale of 1 cm to 5 Newtons?

• 5 cm

• 10 cm

• 15 cm

• 20 cm

What is the length of the arrow representing the horizontal component if it measures 7.1 cm on the scale drawing?

• 35.5 Newtons

• 50 Newtons

• 10 Newtons

• 25 Newtons

In the equilibrium example, what must the resultant of forces A and B be equal to?

• The sum of A and B

• The force C

• Zero

• Twice the force C

Why is it useful to resolve forces into perpendicular components in equilibrium situations?

• To change the direction of forces

• To increase the number of forces

• To simplify the analysis

• To eliminate forces
