  • nice

  • The Equation for calculating angle thi (I am not quite sure how spell it) has a a denominator of 2 multiplied by SQRT of (-a^3)/27. When the value of a is positive, this equation will result in a SQRT of a negative number. How can one calculate this angel in this case? Thank you

  • these are really priceless coaching >>>

    but can anyone say mi any video related to stress tensor problems in this nptel >>

    i require it very much it s not found in any books too

  • forgot to mention a thing-your jandwriting is really great

  • hats off to you Prof. S.K.Maiti

    I appreciate your efforts to make your students understand the subject well

    teachers like you are the real heroes

    you are doing a great service to the society

    please continue your great service to the engineering community

  • Contents:

    * Example on the determination of \sigma_1, \sigma_2 and \sigma_3 and their directions

    * Proof that the principal directions are mutually orthogonal

    * Proof that the roots of the characteristic equation (principal stresses) are all real
