Gravity in hindi language

This is basically what we do with free-body diagrams. We can treat objects, and even systems, as point masses, even if they have very strange shapes or are rotating in complex ways.

What is the center of gravity?

Gravity in hindi language

The center of gravity is the point through which the force of gravity acts on an object or system. In most mechanics problems the gravitational field is assumed to be uniform.

The center of gravity is Gravity in hindi language in exactly the same position as the center of mass. The terms center of gravity and center of mass tend to often be used interchangeably since they are often at the same location.

What about determining the center of mass for a real object? There are a couple of useful experimental tests that can be done to determine the center of mass of rigid physical objects.

The table edge method Figure 4 can be used to find the center of mass of small rigid objects with at least one flat side. The object is pushed slowly without rotating along the surface of a table towards an edge.

At the point where the object is just about to fall, a line is drawn parallel to the table edge. The intersection point of the two lines gives the location of the center of mass in the plane of the table. Table edge method used for finding the center of mass of an irregular object.

The plumb line method Figure 5 is also useful for objects which can be suspended freely about a point of rotation.

An irregularly shaped piece of cardboard suspended on a pin-board is a good example of this. The cardboard pivots freely around the pin under gravity and reaches a stable point.

A plumb line is hung from the pin and used to mark a line on the object. The pin is moved to another location and the procedure repeated. The center of mass then lies beneath the intersection point of the two lines.

Plumb line method being used to find the center of mass of an irregular object. Center of mass and toppling stability One useful application of the center of mass is determining the maximum angle that an object can be tilted before it will topple over. Figure 6a shows a cross section of a truck.

The truck has been poorly loaded with many heavy items loaded on the left-hand side. The center of mass is shown as a red dot. A red line extends down from the center of mass, representing the force of gravity.

Gravity acts on all the weight of the truck through this line. Should the angle be further increased then the point of support will move outside of any point of contact with the road and the truck is guaranteed to topple over.Define gravitate. gravitate synonyms, gravitate pronunciation, gravitate translation, English dictionary definition of gravitate.
