4 Technology in sport

1. Read and memorize the following words:

powerful

потужний

bend

згинати

hit

ударяти

friction

тертя

impact

удар, поштовх

erode

стирати

compression

стискання

fatigue

утома

squeezing

стискання

weaken

ослабляти

tension

напруга

resist

опір

stretching

розтягування

impact-resistant

ударостійкість

2. Read and translate the text.

Modern sports materials are subjected to powerful forces. When a racket hits a ball, the impact causes compression and tension, and may cause bending Repeated friction makes clothing wear away. A bicycle pedal may break because of fatigue if it is turned the same way repeatedly.

Sports materials must have properties to resist these forces. Equipment must be impact-resistant, fatigue-resistant, and tough Clothing must be wear-resistant, fit the body tightly and be aerodynamic Some materials should be rigid, others need to be flexible, or elastic. Some equipment must be hard. For fast sports, equipment needs a high strength-to-weight ratio (combining strength with lightness).

Special materials are used for making modern sports equipment and clothing:

  • Plastics – these are light and can be moulded into shape. Examples: polycarbonate (goggle), polyurethane (footballs), and polysterene ( inside bike helmets)

  • Fibres – materials such as lycra and Kevlar are used for sports clothing

  • Composites – these combine fibres and plastic and have a good strength-to-weight ratio. Examples: fiberglass (boats), graphite, and carbon-fibre (bicycle frames)

  • Laminates – these are formed from two or more layers of plastic or composite metals such as titanium, and aluminium, and alloys such as chrome-molybdenum (cro-moly) combine lightness, strength, and corrosion-resistance.

3. Match the words with their similar meaning.

1 compression

a) characteristics

2 tension

b) stretching

3 wear

c) difficult to break

4 fatigue

d) able to bend

5 properties

e) erode

6 to resist

f) able to change shape and return to their original shape

7 tough

g) squeezing

8 be aerodynamic

h) fight against

9 to be elastic

i) able to move smoothly

10 to be flexible

j) weakending
