The use of strain gauge rosettes was pivotal to the determination of this relationship; they were used to measure the principal strains from which the principal stresses and rosette orientation were derived.

Experimental: Preparation of Soap 1.) The specified graduated cylinder was used to measure 12 mL of oil. The graduated cylinder and the oil, were weighed and the mass was recorded. The oil was transferred into a 125 mL Erlenmeyer flask. The empty graduated cylinder was reweighed. 40 mL of 95% ethanol and 10 mL of 25% NaOH were added to the Erlenmeyer flask. 2.) The flask was placed into a hot water bath.
