Answer:

Explanation:
given data
Load P = 35 kN
Width of bar W = 50.8 mm
Breadth of bar B = 25 mm
Ratio of crack length to width α = a/W = 0.2
solution
we get here KI for a rectangular bar that is express as
................................1
here Y is the geometrical function
so
Y =
Y =
Y =
Y = 0.9878
so put here value in equation 1

= 5210.45 × 10³
= 5.21 MPa 
Answer:
The resulting strain is
.
Explanation:
A specimen of copper having a rectangular cross section 15.2 mm × 19.1 mm
Force, F = 44,500 N
Th elastic modulus of Cu to be 110 GPa
The resulting strain is given by the formula as follows :

E is elastic modulus of Cu is are of cross section

So, the resulting strain is
.
I’m pretty sure it is given to your supervisor . If it isn’t then it’s inspected and repaired
Answer:

Explanation:
For close gas turbine:
Gas turbine works on Brayton cycle.Gas turbine have lots of applications like ,it is use in aircraft,in land applications etc.
Reheating is the method to improve the efficiency of the gas turbine.In reheating gas is expanding in two turbine instead of one turbine alone.Two turbine like high pressure turbine and low pressure turbine are used for expansion.
In the above diagram 1-2 is a compressor,2-3 heat addition,3-4 high pressure turbine,4-5 reheating of cycle 5-6 low pressure turbine,6-1 heat rejection,
We know that 
Now take
represent the enthalpy of point 1,2,3,4,5,6 in the cycle respectively.
So total heat supplied
=

Net work out put
=
So efficiency 

Answer:
a)True
b)False
c)False
d)True
e)True
Explanation:
a)Yes ,because of toggle position.
b)No ,It is not a kinetic chain.
c)No,The transmission angle is the angle between output link and coupling link.
d)Yes,In this lots of tools are used to find the analysis of solution.
e)Yes,Dimensional synthesis can be used for a form of both qualitative syntheses and quantitative syntheses.
