The centre of pressure is the same as the geometric centre. And it will be (a+b)/2

juhita:
its not true...center of pressure is not equal to geometric center
Then what is it? for a parallelogram.
For most of the regular geometric figures, centre of mass, centre of gravity are the same as the geometric centre. And I heard about centre of pressure first time. So I assumed it to be geometric centre.
centre of pressure(c.p)=moment of resultend thrust/sum of the individual thrust
Then which point, according to you is the cp?
firstly,we consider an arbitrary pt on the figar ,then find out c.p. on this pt and then this transformed to the holl area
How good are you at integration? I don't want to do it.
