Question

Where is the C.G. of a (1) Scalene Triangle (2) Cylinder

Answer 1

Hint: Here in this question, we have to find the centre of gravity (C.G) of the given two shapes i.e., scalene triangle and cylinder. We have to find the point which the force of gravity can be considered to act and that is the point where the object is in perfect balance, , no matter how turned or rotated around that point.

Complete step-by-step answer:
The centre of gravity (C.G.) is the centre to an object's weight distribution, where the force of gravity can be considered to act. This is the point where the object is in perfect balance, no matter how turned or rotated around that point. Otherwise
The centre of gravity (C.G.) of an object is the point at which weight is evenly dispersed and all sides are in balance.
Now find the centre of gravity (C.G.) of a Scalene triangle.
A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures.
The centre of gravity of the scalene triangle, let us imagine balancing triangular cardboard on the pencil tip. The cardboard will balance on the pencil tip if it is placed at the centre of mass.

The centre of gravity (C.G.) of an Cylinder
a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.
In cylinder centre of gravity lies at the midpoint of the axis of the cylinder .

Note: Centre of gravity is a theoretical point in the body where the total weight of the body is thought to be concentrated. It is important to know the centre of gravity because it predicts the behaviour of a moving body when acted on by gravity and it is also useful in designing static structures such as buildings and bridges.
