A balance scale is level when the items weigh the same. 

A merchant has a balance scale (refer to Figure 21-4) and wants to be able to weigh any item between 1 and 50 pounds, to the nearest pound. How many different weights does he need to buy ... 

Experts speak of perceived risk versus perceived benefit when attempting to understand the teenage trends of marijuana use. Most of our everyday decisions are based on a balanced scale of these two ideas. When deciding to do something, we weigh the pros and cons—the benefits and risks—and then make our decision. It is commonly believed that this risk/ benefit assessment is a primary factor in determining whether or not a teen will use marijuana.

Elaboration knowledge. The mental model here is faintly reminiscent of a balance scale. If two comparable statements can be found, they need to be weighed one against the other. There are only three possible outcomes The first will be greater than the sec-... 

An image commonly used for this competition is the relationship between things on the right and left pan of a balance scale (Fig. 1). The direction in which the scale tips depends solely upon the sum of the weights G on each side of it. Even negative weights are allowed if objects floating upwards (maybe balloons) are attached to the scale. 

This behaviour can also be expressed formally The left side wins, i.e., the objects A, A",... on the left side of a balance scale or seesaw are successful against the objects B. B",... on the right side in their attempt to sink downward if... 

Each operator shall be instructed to watch for possible malfunctions of balances, scales, etc. When malfunction exists, the balance, scale, etc. shall not be used until repaired. Appropriate records or tags shall be maintained to show data of last calibration and identification of person or company performing the calibration. 

We would have done well to buy that tobacco anyway, American contracts or no American contracts, I said. It s a matter of policy. We haven t learned yet how to do these things we don t have a clearly balanced scale of values. ... 

Therefore, every feasible reaction may be viewed as representing a kind of balance scale that enables us to compare potential values or their sums, respectively. However, the measurement often fails because of inhibitions in the reactions in other words, the scale is stuck. In the case of a drop in the chemical potential from the left to the right side, this means that in principle the process can proceed in this direction however, it does not mean that the process will actually mn. Therefore, this drop is a necessary but not sufficient condition for the reaction considered. This is not really surprising. An apple tends to fall downward, but it will not fall as long as it hangs from its stem. The coffee in a cup does not flow out over the table although the tendency to do so is there. The porcelain walls of the cup inhibit it from... 

Mass is a measure of the amount of material in a substance, such as metal, plastic, wood, brick or tissue, which is collectively known as a body. The mass of a body remains constant and can easily be found by comparing it on a set of balance scales with a set of standard masses. The SI unit of mass is the kilogram (kg). 

A beaker taken from a water bath should be dried on the bottom before it can be placed on a balance scale.

Scales and Balances. The measurement of mass or weight (these terms, though often used interchangeably, are technically different) is carried out using scales and balances. A balance functions by directly comparing the mass to be determined with masses that are known. The two are deemed equal when a properly constructed balancing scale indicates equality. 

Beam-balance scales used to weigh large trucks work on the same principle as the smallest pan balances. The international standard prototype kilogram is a cylinder made of 90 percent platinum and 10 percent iridium. The cylinder is precisely 39 mm high and 39 mm in diameter. 

Force measurements are usually based on a measurement of the motion which results from the applied force. If the applied force results in gross motion of the controlled output, and the mass of the output element is known, then any appropriate accelerometer attached to the controlled output produces an output proportional to the applied force (F = Ma). A simple spring-balance scale (Fig. 18.6(a)) relies on measurement of displacement, which results from the applied force (weight) extending the spring. 

Principle 1. An algebraic equation is structured like a balance scale. The products on the left equal the products on the right. For example ...
