Question

Calculate the x coordinate of the centroid of the shape below. Take A=22mm * 4A

Answer 1

88 44. 14.67 132 3II C2 102.67 L 132

As you can see in Fig. This shape is. made up of two shapes I) Rectangle 2) Triangle centroid of this two shapes are shown in Fig by ci & c2.. . I (44,60) 132 cl 1321 x 144,132) . (2. kun Area Areg .A=88x132 I xuux 132 A = 11616 mm [x, = 44mm 1 A2 = 2904 mm? 1 * = 14.67|mws X2=88+14.67 ) X2 = 102.67 n = 2 i 18 SWIWI T = A, X, + Az X2 ArtA2.

X = (11616X44)+(2904 (14.67786)) 11616 + 2904 18= 55.73 mm Le mo)

X coordinate of centroid is 55.73 mm. I have checked this in software also.

Y coordinate of centrioc is 61.60 mm.

I hope this solution would help you to clear your doubts.

Thank you and Good luck..
