Answer:
i) SF = 0.83
ii) 10 psi
iii) 3.16 psi
iv) 0.0083
Explanation:
Constant load = 1000 Psi
mean resistance = 1200 psi
Probability of failure = 1.9 * 10^-3
<u>Determine </u>
<u>i) Safety factor </u>
S.F = 1 / (mean load / load design ) = 1 / ( 1200 / 1000 ) = 0.83
<u>ii) Standard deviation </u>
1.9 X 10^-3 = e ( -1/2 ( μ / б) ^3 / (2.5 * 6 )
0.004756 = e^- 20000 / б^3
hence std = 10 psi
<u>iii) Variance </u>
= = 3.16 psi
<u>iv) coefficient of variation </u>
Cv = std / mean resistance
= 10 / 1200 = 0.0083

Answer:
Explanation:
Given
From Clausius inequality
=Reversible cycle
=Irreversible cycle
=Impossible
(a)For
Rejected heat
thus it is Impossible cycle
(b)
Possible
(c)Carnot cycle
and maximum Work is obtained for reversible cycle when operate between same temperature limits
Thus it is possible
