1.	The brittle material directly fractures without yielding when it reaches the ultimate strength material.(a) True(b) FalseI had been asked this question during an interview for a job.My doubt stems from Relationship between Tensile and Shear Yield Stress in division Types of Die & Metal Forming Processes of Casting-Forming-Welding II
Answer» Right answer is (a) True For explanation: The behaviour of the material is completely DEFINED by its stiffness. Such material directly fractures without yielding when it REACHES ultimate strength material. These materials are called as brittle materials. Examples of brittle material are ceramics, cast iron, etc. These materials are not suitable for FORMING operation, where permanent plastic deformation is required to GET the final product.
