Question

Center of gravity of the figure shown will be

.






Option 1:
(3.45 , 4.52)

Option 2:
(3.59 , 7.42)

Option 3:
(3.66 , 8.84)

Option 4:
(3.88 , 8.88)​

Answer 1

Answer:

The center of gravity is given by, y = (a1y1 + a2y2) / (a1 + a2) = (50×20/3 + 100×10) / (50+100) = 8.88cm. This will on for the y-axis. For the x-axis, The center of gravity is given by, x = (a1x1 + a2x2) / (a1 + a2) = (50×6.66 + 100×2.5) / (50+100) = 3.88cm.
