A spring-loaded access panel is tested using two different springs, R and S. Each spring is tested separately. Both springs remain in the linear elastic region during the tests.
| Spring | Applied force | Original length | Length under force |
|---|---|---|---|
| R | 4.8 N | 0.080 m | 0.104 m |
| S | 4.8 N | 0.095 m | 0.107 m |
Calculate the spring constant of spring R and the spring constant of spring S.
The panel is then tested using spring R. The length of spring R changes from 0.080 m to 0.115 m. Calculate the force applied to spring R.
