Context and question: Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.
 How can the speed of larger brushes be decreased?
Answer: unanswerable
Context and question: A nonprofit organization (NPO, also known as a non-business entity) is an organization whose purposes are other than making a profit. A nonprofit organization is often dedicated to furthering a particular social cause or advocating for a particular point of view. In economic terms, a nonprofit organization uses its surplus revenues to further achieve its purpose or mission, rather than distributing its surplus income to the organization's shareholders (or equivalents) as profit or dividends. This is known as the distribution constraint. The decision to adopt a nonprofit legal structure is one that will often have taxation implications, particularly where the nonprofit seeks income tax exemption, charitable status and so on.
What is the constraint on how shareholders distribute funds called?
