Answer:
This should be true because program is a software and mouse and keyboard are specific computer hardware to make your exsperience with a computer more efficent and faster.
Answer:
The compressive stress of aplying a force of 708 kN in a 81 mm diamter cylindrical component is 0.137 kN/mm^2 or 137465051 Pa (= 137.5 MPa)
Explanation:
The compressive stress in a cylindrical component can be calculated aby dividing the compressive force F to the cross sectional area A:
fc= F/A
If the stress is wanted in Pascals (Pa), F and A must be in Newtons and square meters respectively.
For acylindrical component the cross sectional area A is:
A=πR^
If the diameter of the component is 81 mm, the radius is the half:
R=81mm /2 = 40.5 mm
Then A result:
A= 3.14 * (40.5 mm)^2 = 5150.4 mm^2
In square meters:
A= 3.14 * (0.0405 m)^2 = 0.005150 m^2
Replacing 708 kN to the force:
fc= 708 kN / 5150.4 mm^2 = 0.137 kN/mm^2
Using the force in Newtons:
F= 70800 N
Finally the compressive stress in Pa is:
fc= 708000 / 0.005150 m^2 = 137465051 Pa = 137 MPa
Answer:
the percent increase in the velocity of air as it flows through the dryer is 12%
Explanation:
given data
density of air ρ = 1.18 kg/m³
density of air ρ' = 1.05 kg/m³
solution
we know there is only one inlet and exit
so
ρ × A × v = ρ' × A × v' ........................1
put here value and we get
= 1.12
so the percent increase in the velocity of air as it flows through the dryer is 12%
Answer:
Explanation:
The following code is in C# Language
public class Circle
{
private float radius;
public float Radius
{
get { return radius; }
set { radius = value; }
}
public void GetArea()
{
Console.WriteLine("The area of the circle is ", Math.PI* Radius *Radius);
}
Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy by the use of centrifugal force acting on the fluid. These are the most popular and commonly used type of pumps for the transfer of fluids from low level to high level.
