What is the difference between a regular machine and a simple machine?
The kinds of simple machine are: Lever, Inclined Plane, Wheel and Axle, Screw, Wedge, Pulley. Lever is a rigid bar that turns or pivots on a fired point called fulcrum. It is used to push, pull or lift objects using less force. Inclined Plane is a ramp or scope that reduces the force you need to exert in lifting something. Wheel and Axle is a device in which a small wheel is attached at the center of a larger wheel. Screw is a inclined plane wound around a post. Wedge is used to cut, split or divide objects.It is made up of 2 inclined planes put back to back to form a sharp edge. Pulley is used to raise and to lower objects.It is a grooved wheel that turns on an axle and acts as lever, a simple machine which consist of small wheel with groove on a rope.
How Is a cockscrew a simple mechanism?
In terms of appearances, to some extend in terms of manufacture, and in terms of mechanical complexity and ease-of-use, a corkscrew most certainly is a simple mechanism: a single part of wound wire, with a sharpened tip at one end and a handle at the other; mechanical devices do not get much simpler than that. However, if you were to analyse the forces within that corkscrew as it is wound into a cork, pulls the work out of the bottle, and is then wound out of the pulled cork, you'd probably find that the mathematics required to describe the physics of these seemingly simple processes, and the forces involved, to be astonishingly complex.
How does the Screw Pump work?
The trick to designing a screw pump is to set the slope of the shaft so that the water caught in the flanges in constantly flowing uphill. ADDED: Assuming this means the Archimedean Screw, a screw thread is essentially an inclined-plane wound into a helix, so it acts rather like a long wedge in raising the material it is acting on. For raising a fluid the screw also needs to be a suitably close fit in its cylinder to minimise leakage round the thread crest.
What factors are considered in the selection of dc machine?
The initial factors are the working voltage and power level required. These set the size of the machine. There are three types of dc machine depending on how the internal magnetic field is produced. A permanent magnet machine gives a constant excitation field and is preferred for smaller motors since no field winding is needed and the machine is therefore simpler. A shunt-wound machine has the field winding in parallel with the armature (the rotating part) and is the commonest type of dc machine. This is used for high-power motors or generators (they are the same thing) where the speed of operation is fairly constant. A series-wound machine has the field winding in series with the armature. This type is used in traction, to drive trams and trolley-buses. The torque produced by a dc machine is proportional to the field current and also to the armature current, so a series motor produces torque proportional to the square of the current. When starting, the motor draws a high current limited only by the resistance in circuit, so the torque is very high and suitable for starting the vehicle. A switched starting-resistor keeps the current within limits. A standard shunt-wound motor acts as a motor when a mechanical load is applied, but if the motor is driven faster than it rotates naturally without a load, then power flows back into the supply and it becomes a generator. A shunt-wound motor tends to behave as a capacitor because the starting current is high and it then reduces exponentially as the rotor gathers speed. If the supply is disconnected, the terminal voltage reduces exponentially as the speed runs down. In a capacitor the energy is stored in the electric field while in the dc machine it is in the kinetic energy of the rotor.
Why has a screw threads?
The threads are what make it work. As you will know if you have tried to use a screw with stripped threads, it is useless. That is because a screw is a simple machine built from an even simpler machine: the inclined plane. The threads are an inclined plane wound around the outside of the screw, and are what change the twisting motion into a lifting motion.

Is a screw like a simple machine wound up?
Yes. A screw is just a ramp twisted around a center post.
