Topic 6 Notes - Designing With Forces

Question 1

What is the purpose of distributing a load throughout a structure?

Answer 1

To ensure no one part is carrying most of the load

This method helps in maintaining structural integrity.

Question 2

How should forces be directed along angled components?

Answer 2

So that the forces hold pieces together instead of pulling them apart

This technique enhances the stability of the structure.

Question 3

What is the significance of shaping parts in design?

Answer 3

To withstand the specific type of force that they are likely to experience

Proper shaping can prevent structural failure.

Question 4

Name three methods for adding strength to structures.

Answer 4

• Arches
• Cantilevers
• Braces

Each method contributes differently to the overall stability and strength of the structure.

Question 5

What are arches in structural design?

Answer 5

Curved components that direct forces relatively evenly along their perimeter

Arches are effective in distributing loads.

Question 6

Define cantilevers in the context of structural design.

Answer 6

Long spans supported at one end

Cantilevers are used in bridges and balconies.

Question 7

What role do braces play in structures?

Answer 7

They add support and rigidity to structures

Braces help prevent deformation under load.

Question 8

How can friction be used to give structures strength?

Answer 8

Through methods like spiral nails, brick and mortar, cement/concrete

Friction helps in holding components together.
