Synopsis
A device is described for recording the maximum force imposed, by the impact of a falling steel rod, on egg shells. Maximum force occurred at the point of shell failure. Correlation between the maximum force during impact and shell thickness were highly significant but not considered adequate for predictive purposes. It was concluded that shell thickness accounted for only part of the variation in resistance of the shell to impact.
