Find the centroid of a triangle?
Centre of area for plane triangle (no thickness, theory only) Line from apex to middle of opposite side, repeat for another apex, intersection is centre of area. > If triangle has thickness go from centre of area vertically down to half thickness of material. This is the centre of mass or centroid
Why does the area of the base affects stability?
An object is stable if the centre of mass of the object is above the base area. A small perturbation of the object is more likely to push the centre of mass outside the base area if it is small.
What is the centre and area in cm of a circle whose circumference cuts through the points of 1 0 and 7 -6 and 7 0 on the Cartesian plane?
It works out that the centre of the circle is at (4, -3) on the Cartesian plane and its area is 56.549 square cm rounded up to three decimal places.
What is the name of that radius which passes through the center of gravity?
Centre of area of a triangle is the centre point for a circumscribed radius which will pass through all 3 vertices of the triangle.
How did you find the Force on inclined submerged plane surface?
The best way is to find the centre of surface of planar area. Then the force due to hydrostatic pressure will be:F = d h0 g S,where:F is force,d is density of fluid,h0 is depth at the centre of surface,S is surface of the area.It works because when we consider the centre of surface, there will exactly as much surface with lesser pressure effecting on it as there is surface below the centre point where the pressure is higher.The net force vector will be perpendicular to the area at the centre of surface point.
