What is the formula for an inclined plane?
It can be divided into two components: Fi = Fg * sinθ – parallel to inclined plane. Fn = Fg * cosθ – perpendicular one.
What is the surface of a wedge?
A wedge can be referred as two identical triangles and three rectangles holding the same height but different lengths. It is a polyhedron solid with the five faces, nine edges, and six vertices.
How do you measure the height of a wedge?
Volume of the rectangular right wedge = (b * h / 6) * (2 * a + e) where a and b are the side bases, e is the top edge and h is the height of the rectangular right wedge.
What is the formula of perimeter of sector?
The formula used for the length of the arc of a circle of radius r and subtending θ degrees at the center of the circle isParc=2πr×(θ360) . Adding the two radii arm with the length of the arc results in the total perimeter of the sector that is equivalent to Ps=2πr×(θ360)+2r.
What is the formula of minor sector?
Area of a Sector of a Circle = (θ/360º) × πr2, where, θ is the angle subtended at the center, given in degrees. r is the radius of the circle. Area of a Sector of a Circle = 1/2 × r2θ, where, θ is the angle subtended at the center, given in radians.
What is a minor sector of a circle?
A sector is a region bounded by two radii of a circle and the intercepted arc of the circle. A sector with a central angle less than 180° is called a minor sector.
How do you work out the angle of a sector without arc length?
To calculate arc length without the angle, you need the radius and the sector area:
- Multiply the area by 2.
- Then divide the result by the radius squared (make sure that the units are the same) to get the central angle in radians.
What is the formula of segment?
Area of a Segment of a Circle Formula
| Formula To Calculate Area of a Segment of a Circle | |
|---|---|
| Area of a Segment in Radians | A = (½) × r2 (θ – Sin θ) |
| Area of a Segment in Degrees | A = (½) × r 2 × [(π/180) θ – sin θ] |
How do you calculate a segment?
- Area of Sector = θ × π 360 × r2 (when θ is in degrees)
- Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)
- L = θ × π180 × r (when θ is in degrees)
What is the height of a circle called?
Sagitta – The height of an arc or segment. The sagitta is the height of an arc. It is the perpendicular from the midpoint of the arc’s chord to the arc itself.
What is a point on a circle called?
A circle is a set of all points in a plane that are all an equal distance from a single point, the center. The distance from a circle’s center to a point on the circle is called the radius of the circle. A line segment that crosses the circle by passing through the center of the circle is called the diameter.
