The Moment of Inertia of a Disk and a Ring

- ... After finding the angular acceleration, the experimental moment of inertia was calculated for all the trials by using equation 1 below. I_experimental=(mr_p (g-r_p α))/α (1) In the equation above, Iexperimental¬ is the experimental moment of inertia, m is the mass of the hangar and the added masses, r_p is the radius of the 3-step pulley, and α is the angular acceleration. The experimental moment of inertia calculated using the angular acceleration with the ring was the experimental moment of inertia for the entire system; therefore, the moment of inertia of the ring must be calculated....   [tags: analysis, experiment, laboratory]

The History of the Disk Operating System (DOS)

- The History of the Disk Operating System (DOS) At the outset, before the advent of user friendly operating systems, computers were run using the operating system CP/M (Control Program for Microcomputers). The program itself looked simple, but the complexity of its use meant that not many fully understood how to use it. As the program was also limited in use, since it was designed for 8-bit systems, a new operating system was needed when 16-bit IBM systems came out. IBM tried to purchase CP/M from its inventor Gary Kildall, but he proved to be elusive and refused to sell....   [tags: Technology]

Memory and Memory Hierarchy

- 1.0 Introduction: In computers terminology, any device which is used to store data and different applications is called memory. Memory is one of the essential parts of computers or any electronic device. It enable device to save the data and the instructions which the CPU Central Processing unit require. The term memory is usually used to describe fast and temporary form of storage. Particularly memory is identified by its capacity. CPU will take long time to retrieve data without memory, therefore, the memory exists so that CPU can retrieve data faster (Tyson, 2011)....   [tags: Storage Space, Computers, Technology]

Benefits Of Using Non Contiguous

- Contiguous means all data in one block chunk and nothing else in the middle, from the beginning of the data until the end, there is no space or any other data separating the data, and so is it stored together. Non-contiguous is the opposite, the data is all over the disk or storage device. It is fragmented and there are more sections allocated to other processes. File Allocation Table stores pointers as linked lists within the table for SSD devices and low- capacity flash drives. Disadvantage of FAT is that it becomes inefficient for devices with large data to be stored since FAT requires lots of memory itself (Englander, 2014)....   [tags: File system, Operating system, NTFS]

Physics of Stopping a Bike

- In short brakes are a tool that turn kinetic energy into heat( This is accomplished by applying friction in one way or another. In the case of disk brakes friction is created because the braking mechanism exerts a force on the break pads which pushes them into contact with disk. It is this contact combined with the fact that the disks are rotating that causes kinetic energy to be converted to heat. If the purpose of brakes is to convert kinetic energy into heat, then in order to know how much heat the brakes make requires that we find out how much kinetic energy there is in a moving bicycle....   [tags: physics bicycle]
