This being the first Case studied, the prime objective of the discussion should be to familiarize the class with what is expected of them with respect to Cases. Since the problem has to do with failure in a racing automobile it should be of inherent interest to a large number of students. It should first be established by the class exactly what the problem was. Then the class can pursue the question of what were the nature and magnitude of the loads on the element that failed. This is an opportunity to have the class make free body diagrams, to make estimates of loadings.
Discussion can pursue the question of whether the ball joint was properly used.
The question of the a fix can be considered. Finally, if all the above aspects have been exhausted, the discussion can turn to Mr. Hall as an engineer. Whether his designs were pursued in the automotive racing business. The original Case contains Mr. Hall's actions to solve the problem. To accomplish this modification, however, Mr. Hall had to flatten the left exhaust duct on his cars.
