A manufacturer tests two tubes with the same dimensions for use as camera tripod legs.
Tube R is made from polymer resin. Tube S is made from carbon fibres held together by the same polymer resin.
The maximum force each tube withstands before breaking is shown in the table.
| Tube | Maximum force before breaking in N |
|---|---|
| R | 140 |
| S | 630 |
Name the reinforcement in tube S.
Name the matrix in tube S.
Explain why tube S is more suitable than tube R for supporting a camera. Use the data in the table.
