Question

how to find centre of gravity
​

Answer 1

Answer:

1.Multiply each object's distance from the datum by its weight to find its moment. This gives you the moment for each object. Here's how to multiply each object's distance from the datum by its weight:

The see-saw: 30 lb. x 8 ft. = 240 ft. x lb.

Child 1 = 40 lb. x 1 ft. = 40 ft. x lb.

Child 2 = 60 lb. x 15 ft. = 900 ft. x lb.

2.Add up the three moments. Simply do the math: 240 ft. x lb. + 40 ft. x lb. + 900 ft. x lb = 1180 ft. x lb. The total moment is 1180 ft. x lb.

3.Add the weights of all the objects.Find the sum of the weights of the seesaw, the first child, and the second child. To do this, add up the weights: 30 lbs. + 40 lbs. + 60 lbs. = 130 lbs.

4.Divide the total moment by the total weight. This will give you the distance from the datum to the center of gravity of the object. To do this, simply divide 1180 ft. x lb. by 130 lbs.

1180 ft. x lb. ÷ 130 lbs = 9.08 ft.

The center of gravity is 9.08 feet from the datum, or measured 9.08 feet from the end of the left side of the see-saw, which is where the datum was placed.
