7 (a) State what is meant by simple harmonic motion.[2](b) A small ball rests at point P on a curved track of radius r, as shown in Fig. 7.1.curved track,radius r XFig. 7.1The ball is moved a small distance to
3 (a)State what is meant by simple harmonic motion.[2](b) A trolley o f mass m is held on a horizontal surface by means o f two springs. One spring is attached to a fixed point P. The other spring is connected to an oscillator, as shown in Fig. 3.1.spring trolley spring oscil...
In this case, what is seen is that the machining process is like an equation with many unknowns, the purpose of this and similar studies is to contribute to the reduction of these unknowns and to reach a solution to the problem, in other words, to fully control the process inputs and...
2 (a)State, by reference to simple harmonic motion, what is meant by angular frequency.***[1](b) A thin metal strip is clamped at one end so that it is horizontal. A loadof mass M is attached to its free end. Theload causes a displacement s of the end of the strip, as shown...
Explain what is meant by machine and define the terms mechanical advantage, velocity ratio, and efficiency as applied to a machine. State the relationship between these terms. Explain whether or not a mechanical advantage of a simple machine can be less than 1. Define the term energy. Sta...
You may now wonder what is meant by coherent light. Consider the "Particle in a Box" in Chapter 5, which we used as an introduction to the calculations of Quantum Mechanics. The only energy states which appear for the electron are those for which "standing waves" appear as a function of...
The thing is curiostity is a very strong emotional driver that underpins all of mankinds advancment. The “powers that be” trying in every which way they can to control what is a very natural process that mankinds future critical depends on is not just exhibiting the worst of typical bu...
What is claimed is: 1.A nanoliter rheometer, comprising:a thin motion fiber and a thin substantially stationary fiber,the ends of said motion fiber and said stationary fiber being opposed to each other and are in close proximity and substantially parallel to each other; or the ends of said ...
What is claimed is: 1. A method for determining the state of tonal quality for a piano hammer, comprising selecting a piano hammer of predetermined type from a set of piano hammers, causing the selected piano hammer to strike against a rigidly mounted impact surface having the form of a...
What is claimed is: 1. A system for monitoring the operational health of a refrigeration system, comprising: a sensor operable to measure temperature within a compartment of the refrigeration system; and a control processor in communication with the sensor and configured to receive a series of per...
