explain traingular lamina how it will determine the position of the centre of gravity
Answers
Answer:
A median of a triangle is a line from a vertex to the midpoint of the opposite side. ... The centre of mass of a uniform triangular lamina (or the centroid of a triangle) is at the meet of the medians.
Take a triangular lamina. Make three fine holes at a, b. c near the edge of triangular lamina.
Now suspend the given lamins along with a plumb line from hole ‘a’. Check that the lamina is
free to oscillate about the point of suspension. When lamina has come to rest, draw straight
Tine ad along the thumb line. Repeat the experiment by suspending the lamina through hale ‘b'
and then through hole ‘c’ for which we get straight lines to be and cf respectively. It is noticed
that the lines ad. he and ef intersect each other at a common paint G which is the position of
the centre of gravity of triangular lamina i.e. the point of intersection of medians.
hope this much helps uh ❣️
