Answer:
Explanation:
We can determine each parameter by using the first method of Zeigler Nichols
For this process;
the initial state of the output =
For calculating the gradient, we use the equation:
where.
Time constant relates to the time
∴
To find time t
Recall that:
Using the first method of Zeigler Nichols
Answer:
stress = 8,556 Psi. or (stress = 59 Mpa)
Explanation:
stress = force / area
force P = 3 tons (convert to lbs. for units consistency)
1 ton = 2240 lbs.
P = 6,720 lbs.
steel bar Diameter D = 1 in. (convert to d
Area of steel bar = (π * 1²) / 4 = 0.785 in²
therefore, stress = 6720 lbs. / 0.785 in²
stress = 8,556 Psi.
in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa
Answer:
F= 5 N
V= 4 m/s
Explanation:
Given that fluid is Newtonian fluid .As we know that for Newtonian fluid the shear stress given as
We also know that
Force = shear stress x area of plate
Now by putting the values
Here velocity of fluid profile is linear.
τ= 2.5 Pa
So force = 2.5 x 2
F= 5 N
Now when fluid is replaced by another fluid but force is constant.The height of plate is also constant.
Lets take velocity of fluid is V in the new condition
So we can say that
Now by putting the value
50 x 0.4 = 5 x V
V= 4 m/s
Jack Plane is designed to take off heavy shavings and squares up rough timber to correct size and quickly removes waste wood.
Answer:
