Equipment * Two power packs * Two plug-plug leads * One pair of magnets * Induction coil * Four plug-clip leads * Discharge tubes (Maltese cross‚ electric plates‚ rotating wheel‚ screen display) Theory: This experiment is designed to show you the properties of cathode rays as discovered by Sir William Crookes. Method: 1. Connect the power pack to the induction coil and set it to 6 volts. Adjust the points of the induction

heavily reliant on time management and efficiency. From the rushed mass production of B-17s for the European Theatre of WWII to line service activity on an active airport ramp‚ a common variable exists. Though those two occasions differ vastly‚ both display urgency and determination to quickly produce results. Unfortunately‚ this urgency has the dangerous ability to lead to somewhat inconsistent‚ careless work ethic. An example of this situation is the 1979 crash of a McDonnell Douglas DC-10 out of Chicago’s

Douglas and his wife‚ Helen Pitts. We chose to present our project as an exhibit because we felt that we could display many of our primary resources as well as showcase our ideas visually. We felt we could use many elements of an exhibit‚ such as imagery and color‚ to effectively bring out the mood of this harsh era in history. At first we opted for a rotating board with six panels. We soon realized that we had too much information and resources for just

Rotating drives which make up the magnetic disk are found in hard disk drives‚ floppy disks and optical disks such as DVDs and CDs. The speed of the magnetic disk depends on its rotating drives which are commonly found starting at 4200 rpm going all the way up to 15‚000 rpm. The data transfer time that controls the data that is moving between

History of Computers 4 Slide Rule Napier’s invention led directly to the slide rule‚ first built in England in 1632 and still in use in the 1960’s by the NASA engineers of the Mercury‚ Gemini‚ and Apollo programs which landed men on the moon.

propeller and connecting it to a motor. This motor lies on a free rotating base that rotates above a stand (truss) that supports the whole mill. Rotating the base to face the direction of the wind is achieved by connecting a back rudder to the base. • How does it work? Electric energy generation starts when the wind rotates the propeller blades – that have a specific angle of attack- ‚ thus rotating the motor that works as a generator giving AC power. Changing this

project uses a microcontroller and a pair of sensors (Transmitter and receiver) which gives the output to the microcontroller. The timer and the counter of the microcontroller gives the speed of the rotating shaft. The microcontroller is interfaced with an LCD to display the speed. The LCD directly displays the speed of the device in rpm. The controller is selected based on the high processing frequency it needs to meet. The concept of the contact-less tachometer can be enhanced and implemented in
