The shear force diagram is always the slope of the bending moment diagram. a)True b)- False
1 answer:
Answer:
True
Explanation:
Shear force diagram is a diagram which is drawn by calculating the shear force either to the right of the section or to the left of the section .
shear force is also be define as the change of moment w.r.t to distance
V=
where V is shear force and M is bending moment.
from the equation we can clearly say that shear force diagram is slope of bending moment diagram.

Answer:
R= 1.25
Explanation:
As given the local heat transfer,
But we know as well that,
Replacing the values
Reynolds number is define as,
Where V is the velocity of the fluid and \upsilon is the Kinematic viscosity
Then replacing we have
<em>*Note that A is just a 'summary' of all of that constat there.</em>
<em>That is </em>
Therefore at x=L the local convection heat transfer coefficient is
Definen that we need to find the average convection heat transfer coefficient in the entire plate lenght, so
The ratio of the average heat transfer coefficient over the entire plate to the local convection heat transfer coefficient is
