Basically for the last three hours I have been struggling with this question.
"Calculate the position of the centroid of a symmeterical t-section having a verticle stem 40mm wide by 120mm high, and a top section which is 80mm wide and 40mm high."
The answer is meant to be 92mm but I have no idea how this was achieved. I tried splitting it into two rectangles but there isn't a way for me to draw a line to find the centroid.
Can anyone help me?
How do you calculate the position of a centroid? watch

Divide the T into an L shape and rectangle, and find the position (L) for the L shape then the rectangle (R).
Join by a line LR.
As the figure is symmetrical, the position (C) for the T must lie where LR intercects AB, the line of symmetry for the T.
