Moments, Centre of Gravity, Centre of Buoyancy, etc. 49 Let ABCD, Fig. 32, be a trapezium. Draw the diagonalsAC, BD, intersecting at E. In the figure CE is greater than … Fig. 32. EA, and DE is greater than EB. Make CH = EA and DF= EB. Join FH. Then the centre of gravity of the triangleEFH will also be the centre of gravity of the trapezium ABCD. (A useful exercise in drawing would be to take a trapeziumon a large scale and find itscentre of gravity by each ofthe…
