) Chain drive ratio is a the ratio between the rotational speeds of the input and output _________ of a roller chain drive system.

Answers

Answer 1

Answer:

Sprockets.

Explanation:

A chain drive is an efficient technique used for the transmission of mechanical power from one point to another. For example, it is used for transmitting power to the wheels of a bicycle, motorcycle, motor vehicle and other machineries such as chain saw etc.

Chain drive ratio is the ratio between the rotational speeds of the input and output sprockets of a roller chain drive system. This ultimately implies that, chain drive ratio is the ratio of the number of teeth on the driving sprocket (T1) divided to the number of teeth on the driven sprocket (T2).

Also, the chain drive ratio can be calculated by dividing the number of teeth on the large sprocket by the number of teeth on the small sprocket.

Additionally, the rotational speed of a sprocket is measured in revolutions per minute (RPM).

One of the issues with the roller chain is that, as the roller chain moves round the sprocket link by link, it affects its speed (surge) due to the change in acceleration and deceleration i.e the rise and fall of its pitch line.

A method used to control density and overcrowding by restricting setbacks, building height, or ratio of open area is known as _________ zoning.

Answers

Answer:

Bulk zoning.

Explanation:

Zoning is a method used by municipal authorities or government authorities to divide a land area into zones. It is a urban planning method. There are several types of zoning; bulk zoning being one of them.

Bulk zoning can be defined as a set of regulations used to control lot size, ratio of floor area, open space, yards, setbacks, bulding height, etc. These setbacks and restrictions, then, help authorities to determine maximun size of a building on a zoning area, and also the positioning of the building.

Therefore, bulk zoning is the correct answer.

However, motors are designed so that the polarity of the electromagnet constantly flips. That is, the north pole becomes the
south pole, and the south pole becomes the north pole, every time the electromagnet turns 180 degrees
Why is it designed this way?
OA.
OB.
Oc.
OD.
to conserve the energy in the battery
so the magnetic field will get stronger
so the electromagnet will continuously turn
to constantly polarize the field magnet
