|What is the centroid for human body?|
|Addisu said: (Feb 8, 2014)|
|The use of centroid is. It tells you at what point the given object is in equilibrium (balance).|

|I need to find the centroid of the human body for both a standing and seated position as part of design that I am putting together for an adaptive wheelchair design for a handicapped individual.
If anybody can please explain to me how to go about finding the overall centroid of a seated and standing human being I would greatly appreciate it.
I am assuming that you just make an assumption that the limbs and torso can be approximated as rectangular sections, with the head approximated as a circle.
If someone can give me a quick calculation or run-through of how this would be done, I would greatly appreciate it.
Thanks for your assistance.

|a1 = pixr^2 = pix25^2 = 1963.5;
a2 = 110 * 25 = 2750;
a3 = pixr^2 = pix12.5^2 = 491;
y1 = 25; y2 = 105; y3 = 172.5.
= (a1y1 + a2y2 + a3y3) / (a1 + a2 + a3) = 85mm.

|My Answer does not match with the given options.
The correct answer is 81.19 please do check the calculations once again.

|I think 81.2 mm is the correct answer.|
|Mithun Raju N said: (Jan 9, 2017)|
|However the nearest available option is 85.9 for 81.18. So we need select the option C.|
|Ajit Kumar said: (Feb 3, 2018)|
|81.20 is the correct answer.|

|Please tell, how did you get y3?|
|Shashi said: (Nov 13, 2018)|
y3 is measured from base to half of the top circle. i.e dia 25 mm so half means 12.5mm
therefore from base 172.5= 50+110+12.5.
