The beam (in black) supports a parabolic laminar sheet . The weight of the sheet is 200N.
Assuming the beam to be massless, find the normal reactions from the two wedges.

    same result normal reaction by the left wedge = 50 N, by the right wedge = 150 N

    for finding center of mass of lamina i had to use some integration...

    i got the answer
    ..
    is there any other way for it.....?????

    @kunal i just find out com's x coordinate of the two lower extremes
    then x coordinate of com of first com and left most region which came to be there centre
    so after applying the definition of com yields the answer
    but lastly i am not convinced by my approach
    so please post ur attemt too.
