In general, speech acts are acts of communication. To communicate is to express a certain attitude, and the type of speech act being performed corresponds to the type of attitude being expressed.For example, a statement expresses a belief, a request expresses a desire, and an apology expresses a regret.s an act of communication, a speech act succeeds if the audience identifies, in accordance with the speaker's intention, the attitude being expressed. Some speech acts, however, are not primarily acts of communication and have the function not of communicating but of affecting institutional states of affairs.
Press down on the gear shift to put the motorcycle into first gear. This only works if you are in neutral or second gear, otherwise, pressing down the gear shift will only take you to a lower gear. Move the gear shift upwards to reach the remaining gears.
An advantage of gears is that the teeth of a gear prevent slippage. When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.wo or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source.
