To find out its CG, we need to draw the diagonals for each of part A, B, and C then find the intersecting points of the above diagonals which gives us the centres of gravity of each of the three ‘pieces’ of the shape. These are shown by CG1, CG2, CG3 on the diagram.
How do you center in AutoCAD?

What is the center of gravity?
Your centre of gravity is the point where the mass of the body is concentrated. The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated.
How do you create a region in AutoCAD?
Define Regions Click Home tab Draw panel Region. Find. Select objects to create the region. These objects must each form an enclosed area, such as a circle or a closed polyline. Press Enter. A message at the Command prompt indicates how many loops were detected and how many regions were created.
What is the difference between a fillet and a round?
A fillet or round connects two objects with a tangent arc in 2D, or creates a rounded transition between the adjacent faces of a 3D solid. An inside corner is called a fillet and an outside corner is called a round; you can create both using the FILLET command.
What is a mass property?
Mass properties determine how your mechanism resists a change in its speed or position upon the application of a force. The mass properties of a mechanism are its density, volume, mass, center of gravity, and moment of inertia.
What is an AutoCAD region?
Regions are 2D areas that you create from closed planar loops of objects. Valid objects include polylines, lines, circular arcs, circles, elliptical arcs, ellipses, and splines. Each closed loop is converted into a separate region. All crossing intersections and self-intersecting curves are rejected.
How do I center a rectangle in AutoCAD?
Centering an Object Inside a Rectangle Select the 2 Point option from the Command line. Snap to the mid-point of one of the horizontal lines then snap to the insertion point of the text. The text will move to align vertically with the center of the rectangle.
How do you find the center of a square?
Squares and rectangles are pretty easy, you simply draw two diagonal lines from the opposite corners and the point where they cross is the center of your material. You can even use the side of the box it came in as the straight edge!.
How do I center align text in AutoCAD?

Which function key toggles osnap in AutoCAD?
F3 – Toggles the Osnap tool on and off.
How do you find the centroid of a shape?
To calculate the centroid of a combined shape, sum the individual centroids times the individual areas and divide that by the sum of the individual areas as shown on the applet. If the shapes overlap, the triangle is subtracted from the rectangle to make a new shape.
What is the formula to find the center of gravity?
Taking the sum of the average value of the weight/volume times the distance times the volume segment divided by the weight will produce the center of gravity.
How do you balance center of gravity?
To balance a ruler horizontally on a finger, the finger must be directly under the ruler’s centre of gravity. In this case, the ruler’s centre of gravity is the same as its mid-point since the ruler is symmetrical and has equal mass along its length.
