Question

why do the lines intersect on the single point while locating tge center of gravity of a irregular card board lamina​

Answer 1

Answer:

The intersection of the three lines must be the center of gravity because the center of gravity of an object is the point through which the total weight of the body can be considered to act. The point where the total mass of the body seems to act is the center of gravity.

Answer 2

Answer:

Because an object's centre of gravity is where the entire weight of the body is thought to act, the intersection of the three lines must be the location of the centre of gravity.

Explanation:

• Make holes at the corners of A, B, C, D, and E so that you can suspend the cardboard at each one in turn while using the plumb line's thread to draw a line beneath the thread in order to determine the centre of gravity of an irregular body.
• The location where the greatest number of lines converge is the centre of gravity.
• A body of matter's centre of gravity is a hypothetical location where, for the sake of convenience in some computations, the body's total weight may be assumed to be concentrated.

Thus, when locating the centre of gravity, the lines intersect on a single point.
