Abstract
A testing device for measuring a lateral pressure induced on a material by a vertical applied pressure, the testing device comprising in combination a material-holding receptacle which is capable of lateral expansion in response to a vertical applied force on a material contained in the receptacle, and a sensing means positioned on the receptacle to sense the amount of lateral expansion of the receptacle.
