Answer:
=0.60
Explanation:
Given :Take =1.4 for air
=r ⇒ r=16
As we know that
So
=909.42K
Now find the cut off ration
So efficiency of diesel engine
Now by putting the all values
So =0.60
So the efficiency of diesel engine=0.60
Answer:
Hello the required diagram for the question is missing attached is the diagram AND A FREE BODY DIAGRAM
B)Rav = 3.375 KN Rbv = 4.625 KN
Explanation:
Attached is the detailed diagram of the bending moment diagrams and shear force
A) using singularity functions
y(x) = Displacement shape of Elastic curve
dy/dx = ∅ (x) ( slope )
d^2x/dy^2 = m(x) / E I ( moment function )
d^3x / dy^3 = I / EI V(x) ( shear function )
d^4x / dy^4 = I / EI q(x) ( loading function )
B) using the appropriate boundary conditions find out the constants
summation of F(x) = 0
Rah = 0
Rav - 8 + Rbv = 0
Rav + Rbv = 8 ----- equation 1
summation of M(a) = 0
= -8(4) + Rbv (8) - 5 = 0
therefore Rbv = 37 / 8 = 4.625 KN
insert the value of Rbv back into equation 1
Rav = 8 - 4.635 = 3.375 KN
C) ATTACHED ARE THE DIAGRAMS
