"These are two separate principles in physics that are intertwined in how they together modify the shape of an object. In simple terms, stress is the proportion of force or pressure applied over an area of an object. Strain is the proportion of deformation of an object as a result of the stress. The deformation takes form as a result of either normal strain or shear strain."

There are a variety of technical questions you may be asked in your SpaceX interview. Not only does this interview question test your basic knowledge and qualifications, but it also tests how you communicate. Not everyone is a skilled verbal communicator who can explain complex concepts in simple terms. At SpaceX, the standards are high for how efficiently you can work and how well you can communicate and coordinate with others. Consider this when practicing your answer.

"Stress is a measure of the amount of force per unit area that a material can withstand. It is a way to describe what causes a deformation.
Strain is more of a measure of the deformation. Strain is dimensionless and is the ratio of change in length compared to the original length due to stress."

"Stress is a way to measure the effects of various forces (tension, compression, torque, shear, etc.) on a material. Strain is a measurement of the amount of deformation occurring on the material under stress."
