Compression Test on Cast Iron
In brittle failure, the specimen shears off a plane at angle of 45 degree to normal, this is due to
Materials having same elastic properties in all directions are called
During compression test on cast iron, the failure occurs i.e. the crack appears along the
The specimen that would exhibit the least reduction in its cross sectional area at the point of failure would be

The group of materials that vary significantly in their compressive and tensile strength is
