Smaller the value of c (fatigue ductility exponent) ____________ will be the life of component.
Each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet. S1 :The weak have no place here, in this life or in any other life. Weakness leads to slavery.
S6 :This is the great fact : strength is life, weakness is death. Strength is felicity, life eternal, immortal; weakness is constant strain and misery : weakness is death.
P :They dare not approach us, they have no power to get a hold on us, until the mind is weakened.
Q : Weakness leads to all kinds of misery, physical and mental. Weakness is death.
R : But they cannot harm us unless we become weak, until the body is ready and predisposed to receive them.
S :There are hundreds of thousands of microbes surrounding us.The correct sequence should be

What are the principles for ensuring the consistency of an equation through dimensional analysis? Statement I: The sum of all exponents of any dimension (e.g., mass), should be the same on both sides of the equation. Statement II: An exponent must itself be a pure / dimensionless number. Statements III: The magnitude of the exponent does not necessarily have to be a whole number.
