# Numerical - Reason for failure, given principal stress & elastic limit stress

**Q. Principal stress of 30 Mpa and -70 Mpa acts on a material which has elastic limit stress in simple tension and compression as 60 Mpa and 200 Mpa respectively. Specify the reason for failure of the material assuming maximum principle stress theory.***- Published on 23 Sep 15***a.** Compression

**b.** Tension

**c.** Unpredictable

**ANSWER: Tension **
