Given : A symmetrical 'T' shaped lamina is made from two rectangles 10cm X 5cm , so that total height is 15cm.
To Find : The centroidal distance from bottom
Solution:
Centroid of each rectangle would be center point of rectangle where diagonal bisect each other
Hence Height of centroid of 1 rectangle = 10/2 = 5 cm
Height of centroid of 2nd rectangle = 10 + (5/2) = 12.5 cm
(centroid rectangle is at height of 10 cm and 5 cm is its height/width )
As T is symmetrical Hence x coordinate would be same for both rectangles
now Height are 5 cm and 12.5 cm from bottom
and both area identical
Hence The centroidal distance from bottom = ( 5 + 12.5)/2
= 17.5/2
= 8.75 cm
