thanks, but I was only giving some points in the right direction. i was hoping that would have physiker99 think some .. in the future I will keep this in mind and just do the work for them ... i am new to the thread and was under the impression that the questions are not just answered with a...

I would draw the free body diagrams for both objects first ... then remember "In the absence of friction and other forces (tension, applied, etc.), the acceleration of an object on an incline is the value of the parallel component (m*g*sine of angle) divided by the mass (m). This yields the...

ditto

I believe the FE Exam is required for Civil Engineers only... perhaps I am mistaken on that ... and the rest of the Engineering Fields do not have to take the exam .. but the exam is required for all to obtain a PE ... here is the site that should answer all your questions...

Try these formulas ... just a thought TAS = 2 x EAS x (T + 460)/P Reference: http://www.nar-associates.com/technical-flying/airspeed/airspeed_wide_screen.pdf The barometric formula Reference: http://hyperphysics.phy-astr.gsu.edu/hbase/Kinetic/barfor.html#c3 Pressure Altitude...

always opposite the angle is "sin" and adjacent the angle is "cos" .. http://en.wikipedia.org/wiki/Trigonometric_function

Plotting the Frequency Response Using MATLAB The frequency response of a system is the major way of characterizing how a system behaves in the frequency domain. It is important to understand the frequency characteristics of a given system rather than time domain characteristics alone for many...

I would say yes .. take the derivative again .. I think d^2y/d^2x, should read d2y/dx2 ... I have the first derivative to be f' = (3/2) ((sec\sqrt{}x)\cdot(tan\sqrt{}x))/\sqrt{}x

Does anyone have the equation that the absolute roughness is expressed in terms of Manning coefficient, with the reference included? I have found one from Webber 1971. n = k1/6/26 where: n = applicable Manning roughness coefficient, k = absolute roughness (mm) Reference :Webber...
