How calculate the engine work from pressure crank-angle diagram?
Well Work is the integral of P*dV and since the crank angle plot doesn't directly show volume you need to calculate instaneous volume of the cylinder as a function of crank angle. If you know the bore and stroke you can find the volume of the cylinder and you can relate this to the crank angle. Once you have these values you can replace the crank angle with volume and have a P-V plot or pressure on the y-axis and volume on the x-axis. Then you can integrate the area under the curve and find the work from the engine. However, all this is done for you if you can find the P-V diagram for your engine or engine cycle (Sterling, Atkinson, Otto, Diesel, etc.) and integrate this for the work.
How to calculate Q first moment of inertia above and below the neutral axis?
-find the area(A) of the shape above the neutral axis (or above a particular point if given) - locate the centroid (y')of the shape relative to the neutral axis(or above point) using y' = ∑AiYi / ∑Ai - first moment of area = A*y' (or y' + distance of given point from neutral axis)
Can any plane turn or rotate at an angle of 90 degrees and keep flying?
Any plane can make a 90 degree turn on the z axis and keep flying.
What is meant by longitudinal dynamics of aircraft?
Longitudinal aircraft dynamics variables are (small) deviations from operating point or trim conditions state (components): u: velocity of aircraft along body axis v: velocity of aircraft perpendicular to body axis (down is positive) : angle between body axis and horizontal (up is positive) q : angular velocity of aircraft (pitch rate)
Definition of Quadrature axis?
Quadrature axis of a magnetomotive force is defined as that component of MMF that is directed along an axis in quadrature with the axis of the field poles. Quadrature axis of a magnetomotive force is defined as that component of MMF that is directed along an axis in quadrature with the axis of the field poles.
What is the angle of inclination of the earth's axis with its orbital plane?
its 66.5 degrees
Does Steering axis inclination reduces the need for excessive positive camber?
Yes it does
What is dihedral angle on aeronautics?
An upwards inclination of the wings on lateral axis and an included angle is known as dihedral angle.
What sai angle in wheel alignment?
SAI stands for steering axis inclination. It is the angle from the upper ball joint/or upper strut to the lower ball joint. If this "line" is off, it can be an indication that there is a bent steering or suspension part. this is in simple terms, a front end shop can give a deeper explanation and example.
What is the importance of the inclination of the earth axis?
This titled position of the earths axis is known as inclination of the earths axis. The earth's rotation axis makes an angle of about 66.5 degrees with the plane of its orbit around the sun, or about 23.5 degrees from the perpendicular to the ecliptic plane.
What means the tilt of the earths axis?
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs from orbital inclination.
What is a camber angle?
The camber angle is the angle that the wheels of a vehicle make. Specifically, it is the angle between the wheel axis used for steering and the vertical direction of the car.
Is the earth rotational axis of 180 degrees the as 23.5 degrees?
Earth's rotational axis has an inclination of 23.5 degrees. The angle is measured from a line that is perpendicular to Earth's plane of rotation (the Ecliptic).
What is Mars rotation on its axis?
Axis inclination - 23° 59
What is the inclination of axis on mars?
25 deg on its own axis
What is the tilt of Earth's axis called?
The tilt of the earth's axis is called ecliptic. The tilt of the earth's axis will vary in most cases between 22.1 and 24.5 degrees.
What is a king pin inclination?
The kingpin inclination is the angle, measured in degrees, that forms the line passing through the kingpin and the perpendicular to the ground, looking at the vehicle from the front,Wheel camber angle was devised to reduce the kingpin offset, which is the distance between the projection to the ground level of the kingpin axis and the point of contact with the tyre,But it was noted that a marked increase in this angle created negative effects, especially with the tyres at low pressure, the specific need arose, to reduce the camber angle almost to zero, this was also to achieve regular wear on the tyre, the problem was resolved by inclining the kingpin towards the lower part of the wheel,With rigid-axle suspension systems, the inclination of the kingpin does not vary under the effect of load and the vertical jolting of the vehicle, providing there is no axis deformation, in independent suspension systems, however, the load and vertical jolting of the vehicle cause both the wheel camber and the kingpin inclination to vary to the same degree, as the kingpin forms a single block with the wheel hub,Included angleThe angle between the kingpin axis and the wheel axis is equal to the algebraic sum of the kingpin inclination angle and the wheel camber angle and is defined as the included angle, Example1st case2nd caseWheel camber angle+2 deg-1 deg+ Kingpin inclination angle6 deg8 deg= included angle8 deg7 deg The included angle can vary only if there is a deformation between the kingpin axis and the wheel hub axis, if, during the checking operation, it is noted that the kingpin inclination angle and the wheel camber angle differs considerably from specified values, then before deciding what action to take it is advised to check to see whether the included angle has remained unchanged,ExampleSpecified ValuesObserved ValuesWheel camber+2 deg+1 deg (less than spec,)Kingpin inclination6 deg7 deg (more than spec,)Included angle( +2 deg 6 deg ) = 8 deg8 deg = constant In this case, the likely deformation, or irregular positioning of the parts, will be related to either the suspension arms or the suspension arm mounts, in this case the kingpin and the wheel hub positioning has not changed,If, on the other hand, the following measurements are observed,Wheel camber +1 degKingpin inclination 6 degIncluded angle 7 deg = inconstantThen there is a deformation in the kingpin-hub assembly,The kingpin inclination angle, amongst other thing, creates the phenomena of the return of the wheels to straight position after a steering operation, it also tends to maintain this position after an impact with an obstacle that attempts to alter the trajectory,This natural effect, which is vitally important, due to the inclination of the kingpin, derives from the fact that the wheel, when turning about this oblique axis, forms an inverted cone,The hub is at it's highest point relative to the ground, when the wheels are in the straight ahead position, when steering to the left or right, the hub lowers down nearer to the ground, consequently the wheels would tend to go beneath ground level, as they are unable to do this, this causes the body to rise up into an unstable position, thus, when turning the steering wheel, the driver not only generates the turning of the wheels but also, because of the weight of the vehicle, causes the raising up of the body, as soon as the driver ceases with the steering action, the body, due to the natural tendency by its own weight, goes to it's lowest point, with this movement, causing a turning action which takes the wheels back to the straight line position, obviously, the heavier the vehicle or the bigger the kingpin inclination, the greater will be both the force exerted by the driver in the steering action and the speed with which the steering goes back to the mid position,The evident result of this is that the weight of the vehicle tends to take the wheels to the straight line position, therefore, each perturbation force on the straight line direction of
