Answer 11

A shear force is a force that acts across a material by acting near to one another but not directly opposite. For example scissors

Question 12

What is a bending force?

Answer 12

Forces that act at an angle to an object and make it bend. For example when you place too many books on a book shelf the shelf may bend

Question 13

What is a torsion force?

Answer 13

Torsion forces are twisting forces that are applied to an object. Like when you twist the screw cap off a bottle

Question 14

How can concrete be enhanced to overcome the poor resistance to tension?

Answer 14

It can be reinforced with steel bars which are embedded in the concrete before it sets

Question 15

What forces are concrete good and poor at resisting?

Answer 15

Good at resisting compression

Bad at resisting tension

Question 16

How can fabrics be stiffened?

Answer 16

By having strips of other materials inserted in them

Question 17

How can timber be stiffened?

Answer 17

In the process of laminating

What is mining?

Answer 19

The removal of minerals and metals from the earth

Question 20

What are the drawbacks to mining?

Answer 20

.It contaminates water and threatens communities and indigenous populations
.Deforestation occurs to make space for mining which is bad for the environment

Question 21

What is drilling?

Answer 21

Drilling is the process of extracting liquids and gases from underneath the ground

Question 22

What are the drawbacks of drilling?

Answer 22

.Once oil has been located dangerous chemicals are used to extract it

Question 23

What is the definition of reinforcing?

Answer 23

When two materials are added together to make it stronger

Question 24

What is the definition of webbing?

Answer 24

Webbing is a strong fabric woven as a flat strip or tube of varying width and fibres, often used in place of rope.

Question 25

What is the definition of laminating?

Answer 25

Slicing wood into veneers and gluing those together to make layered wood

Question 26

What is the definition of fabric interfacing?

Answer 26

Adding strips of other materials to fabric by interfacing it

Question 27

What is the definition of folding and bending?

Answer 27

When paper or card is folded, the forces are applied at an angle. This is a bending force on the card.

Question 28

What are the materials involved in farming?

Answer 28

Cattles and crops

Question 29

What are the drawbacks of farming?

Answer 29

Farming uses 70% of the world’s usable water supply which decreases availability. It also destroys wildlife habitats and removes nutrients from the soil

8 million tonnes of plastics are put in the ocean every year which is harmful to wildlife

Question 34

What are the key materials that pollute the atmosphere?

Answer 34

fossil fuels

Question 35

What are the impacts of atmospheric pollution?

Answer 35

Greenhouse gases are produced like sulfur dioxide, carbon dioxide and carbon monoxide. This changes the quality of the air and can cause long term health problems

Question 36

Define the life cycle analysis

Answer 36

he life cycle analysis is the life cycle of a raw material and everything it goes through from the raw form to the end of the products life

Question 37

What are the six Rs that designers must consider when designing products?

Answer 37

Reduce - the amount of energy and materials used in the manufacture of a product

Reuse - the product for something else so you don’t need to throw it away

Recycle - Take the product apart and you can recycle them and make another product

Rethink - products and how we use them. Could there be a better way of doing the same job?

Refuse - to buy materials that are unsustainable

Repair - product rather than throwing them away
