4.11 Motor A DC motor is an electrical machine which converts electrical energy into mechanical energy. A magnetic field is generated by the current carrying conductor and when this system is placed in external magnetic field then the force is exerted which is proportional to the strength of the external magnetic field and to the current in the conductor, then motor will rotate. If the direction of current is reversed then the direction of rotation of motor will also reverse. The speed of DC motor can be controlled by the variable supply voltage or by changing the strength of current. Small DC motors are used in toys, tools, and appliances. Larger DC motors are used in propulsion of electric vehicles, in drives for steel rolling mills, elevator …show more content…

The MAX232 is a dual receiver/driver and it converts the TX, RX, CTS and RTS signals. The drivers provide RS-232 voltage level outputs (approx. ± 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors. The receivers reduce RS-232 inputs (which may be as high as ± 25 V), to standard 5 V TTL levels. These receivers have a typical hysteresis of 0.5 V and a typical threshold of 1.3 V. Figure 4.16: Pin Diagram of MAX232 4.13 RS232 Interface In telecommunications, RS-232 is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DCE (Data Circuit-terminating Equipment) and a DTE (Data Terminal Equipment). It is use to connect the computer serial port to the electronics component like data storage, printers, mice, un-interruptible power supplies, and other peripheral devices. The standard defines the meaning of signals, the electrical characteristics and timing of signals, and pin out of connectors and the physical size. Figure 4.17: RS232 4.14 Motor

Children in this group were provided with base-10 and unit blocks. Each base 10 block is 1 cm × 1 cm × 10 cm in size. Each unit block is 1 cm × 1 cm × 1 cm in size. The research assistant gave explicit demonstrations of how to use both base-10 block and unit blocks to construct two-digit number. First, the research assistant placed out ten unit-blocks in a line and then put a base-10 block along to the ten unit-blocks.

With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.

Unit 5’s reading section covers the various features and tools available in Microsoft’s Powerpoint application (Gambrel, 2014). The first part I found helpful was the section that taught how to create a new presentation. This taught me several things about Powerpoint including how to add, delete, and organize slides. I have used Powerpoint in the past, but everything I know about it is self-taught, so it was good to have an actual training that covered everything from scratch.

1. Perception categories that significantly influenced walking frequency were landuse, and aesthetics and amenities. The safety, directness and continuity perception categories were not significant but had weak to moderate associations with land use and aesthetics perception. This implies improving perception of one category is bound to improve or negatively impact the perception of a correlated category. For example landuse perception was correlated with directness perception - which is intuitive, given that directness measured quick and easy access to land uses.

Break Point 6.2 I think that the students are trying to describe what most people cannot: the effect that music has not on our minds, but our bodies. Because the mind is not involved in this physiological process, one can only begin to describe why we get "pumped," why our heart rates increase or why our moods change when we hear a certain piece of music. In the conversation in Chapter 6, each student seems to have a different way of describing how music makes them feel, which supports my belief that each student has a unique physiological approach when listening to or performing music that is unlike that of anyone else. As the chapter mentions, there is no true explanation as to why some people get goosebumps when a certain song plays and others do not. Personally, my musical tastes are all across the board, and change

PURPOSE The goal of this lab was to build a mousetrap powered car. The mousetrap car needed to travel fifteen feet. The purpose of building these mousetrap cars was to demonstrate our knowledge of motion, friction, force, distance, and energy. We have studied these concepts, and each one is a factor in the success of a mousetrap car.

Wind energy is currently one of the most popular sources of renewable energy due to it being inexpensive, currently competing in price with fossil fuels (Kim and Dah-Chuan Lu 2010). Wind turbines function by using the kinetic energy of the wind to drive the blades of the turbine causing the generator to convert the kinetic energy into electrical energy (Mahela and Shaik 2016). Horizontal axis turbines are the most common type of turbine. Figure 1 the setup of an air turbine with the two most common type of generators these are squirrel cage induction and doubly feed induction generators, with the doubly generators being preferred due to having control of synchronous speed (Wallace 2014).
