Where is physical balance used

Then the lever is turned towards right so that the beam rises and the pointer begins to swing on either side. The side left or right to which the pointer moves more, indicates less weight on that side. The standard weights are adjusted till the pointer either remains at the zero mark of scale or it swings equally on both sides of the zero mark.

In this position, the total mass of weights on the right pan gives the mass of object. Precautions in Using a Beam Balance The weights should be carried with forceps. They should not be carried with bare fingers to avoid the change in its weight due to the presence of moisture and dust particles. Wet and hot objects should not be kept on the pan.

When near the actual weight, the weights should always be tried in the descending order. The beam should be lowered each time before adding or removing weights from the pan.

The weight should be replaced into the weight box after weighting. The lever should be turned gently, in order to prevent the knife edges from chipping.

Conditions for a True Balance A balance to the true , must satisfy the following two conditions: Both arms must be of equal lengths, and Both pans must be of equal weights.

Summary The mass of a body is the amount of matter present in it. There are two types of visual balance: Symmetrical and Asymmetrical. Symmetrical balance refers to an even distribution of visual weight on either side of an axis.

This work as well, once cut in half along the central axis, would have the objects of the two sides match each other perfectly as if reflected by a mirror. Balance refers to how the elements of art line, shape, color, value, space, form, texture relate to each other within the composition in terms of their visual weight to create visual equilibrium.

That is, one side does not seem heavier than another. The principles of design describe the ways that artists use the elements of art in a work of art. Balance is the distribution of the visual weight of objects, colors, texture, and space.

If the design was a scale, these elements should be balanced to make a design feel stable. The principles of landscape design include the elements of unity, scale, balance, simplicity, variety, emphasis, and sequence as they apply to line, form, texture, and color.

These elements are interconnected. Landscape design is a process of developing practical and pleasing outdoor living space. Colors Express Emotions The many colors created through the combination of the three principal color elements known as the three chromatic properties, hue, value, and chroma, express the various color tones. Two similar pans are suspended on two more knife edges near each end of the beam.

An example of balance is when a person divides his time evenly between work, family, and personal pleasure. Common balance is defined as the balance which is having each arm as suspended. The unknown mass is kept in one arm and the known mass in another until they both become equivalent.

Therefore this balance is working on the principle of moment of weights. Answer: If pointer is not in middle of the scale, we move these screws forwards or backwards to bring the pointer in the middle of the scale. This is done before we put any mass or weight in either of the pan. In other words we use the screws to remove the zero error of the physical balance.

The physical balance consists of a light and rigid beam of brass, a metallic pillar, a wooden base, two pans, a metallic pointer, and an ivory scale.
