Using load cells (linear-force and rotational-torque), strain gauges (including rosette gage theory), pressure cells, and a variety of piezoelectric accelerometers, allows us to determine load, stress, and strain in most materials and applications.

Conclusions about manufacturing defects, design defects, and proper usage can be found from the data obtained in testing.

Further data analysis can be conducted to solve for static loads, equations of motion, mechanical behavior, and system response.
