Product Description

Video and lesson investigations on the topic of testing. Key concepts include:

  • Sometimes, doing a full-scale test is the only way to see if a structure is strong enough.
  • Some tests need to take account of extreme, but possible, circumstances.
  • Testing to destruction reveals the strength limits of a design structure and the materials used.
  • Full-scale testing is important where potential risk to life is involved.
  • Full-scale tests are not always possible. For example, full-scale testing the strength of buildings in an earthquake-prone area cannot be done, neither can real bridges be tested to destruction.
  • In this case, models are tested and engineers rely on carefully worked out calculations to ensure safety.
  • Often such structures are built extra strong, enough to withstand twice the amount of stress that can reasonable be expected.
