it is arc angle
The answer does not match. It is called a Radianthat is used in Trigonometry, a special branch of mathematics which deals with study of triangles. "Tri" means three and "gono" means angle and "metry" means measure) . If there is an angle at the center of circle subtended by the arc whose length is equal to the radius, then the angle at the center is called 1 Radian.Extending the math out in order to determine the number of degrees in one radian, this is what we have. C = 2(pi)r; the length of the circumference is 2(pi) times the radius. This means that the number of radii in the circumference is 2(pi); there are 2(pi) radii in the circumference. There are 360 degrees in a circle, so the number of degrees in an angle subtended by an arc one radius long would be 360/2(pi), or about 57.3 degrees.
An isometric view necessarily should have two side views and either top or bottom view incorporated to be drawn in a single drawing. In order to represent top 0r bottom view a 30 degree angle from horizontal will be established as an inclined plane. Hence where the circle has to appear is important. Any how in order to get a circle in an isometric view an oval or elliptical form should be present in any one of the first angle or third angle views.
IUG_DimensionConstraintGstarCAD provides you eight Dimensional Constraint types:LinearConstrains the horizontal or vertical distance between points.Linear(Horizontal)Constrains the X distance between points on an object, or between two points on different objects.Linear(Vertical)Constrains the Y distance between points on an object, or between two points on different objects.AlignedConstrains the distance between points on an object or between two points on different objects.AngularConstrains the angle between line or polyline segments, the angle swept out by an arc or a polyline arc segment, or the angle between three points on objects.RadiusConstrains the radius of a circle or arc.DiameterConstrains the diameter of a circle or arc.ConvertConvert associative dimensions to dimensional constraints.
The angle between chord line and turbine axial direction ( also known as setting angle)
Yes.
Central Angle An angle in a circle with vertex at the circle's center.
An angle that's vertex is on the center of the circle.
An angle with its vertex on the center point of the circle.
central angle
Central angle
No. It's a central angle only if its vertex is at the center of the circle.
Central Angle
true
The central angle is the angle that has its vertex at the center of the circle.
That is the central angle.
