state the following, 1.the principal of moment, 2.the principal of flotation, 3.Archimedes principle

1.

Explanation:

1.The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point.

2.When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation” where a floating object displaces a weight of fluid equal to its own weight.

3.a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
