Mark As Brainliest

Explanation:

So, if you hang a shape from two different points (one at a time) and draw a line straight down from each point, the center of mass is where those lines intersect. This technique can be used for any irregular two-dimensional shape

Draw a line on the object along the string. For Step 2, repeat the procedure from another point on the object You now have two lines drawn on the object which intersect. The center of gravity is the point where the lines intersect. This procedure works well for irregularly shaped objects that are hard to balance

Answer 2

Explanation:

which the position of the centre of gravity of the object depends.?

The position of the centre of gravity of a body of given mass depends on its shape i.e., on the distribution of mass in it. For example, the centre of gravity of a uniform wire is at its mid-point.

You’re given an irregular shaped three-dimensional object. State the factor on ?

What is the center of gravity for a regular and an irregular body?

It is the balance point that the object can revolve upon itself in perfect motion. It is also the moment of inerta of an object…its the exact geometric centre of mass of a symmetrical object.

In an asymmetrical object it is not the geometric centre, but the intersect of xbar ybar zbar.

Each bar represents the average of the incremental dimensions when measuring in x y z axis of the object. The intersect of the averages reaveals the moment of inertia which is always = the centre of gravity in a static state. Inertia changes where the gravitational center is located but always originates in the moment.
