fatigue theory is very important to be developed in mechanical engineeringstudents. 1The fatigue strength or test data should be described by the random variables, that is, statisticalapproach. However, for undergraduate program, fatigue test data are typically described bydeveloping Stress (S) vs. average Cycles (N) to failure (S-N) curves. These curves are thefunctions of stress amplitude, mean stress and the average number of cycles at failure. Thefatigue strength of a component is significantly affected by inherent component defects andloading conditions. As such, the material strength design limit is reduced thru the application ofmodification factors, often linked with component stresses thru

He wants something that will be appropriate for his wilderness resort. After learning of your vast new knowledge of fluid mechanics, he has asked you to design a fountain. As a member of the National Fluid Power Association, Uncle Mort requires that one or more of the nozzles is controlled by a hydraulic system which will allow the nozzle(s) to move the water jet(s) in some sort of pattern. The water jet(s) from the movable nozzle(s) must be high enough pressure to allow for a sufficient water height. He wants this fountain to be an attraction for his customers

results in lower performance averages by students compared to PSVT:R problems forthis population. It is expected, based on Reusch et al.’s results [22], that there is a higherdifficulty level on the MCT problems used. This, in turn, may have been reflected by themoderate increase in EDA when we consider dividing this value by the time expended on theMCT problem-set as can be estimated from the two Figure 3 graphs (e.g., 0.05microSiemens/minute for MCT). The preliminary results of this pilot study corroborate thesefindings by suggesting a higher normalized arousal (or mean range-corrected EDA/timed event)found in these types of problems compared to PSVT:R (0.13 microSiemens/minute) and Staticsproblems (0.01 microSiemens/minute) (Figure 3).Parallel

Students who are generally weaker on this material, as judged bytheir eventual overall score in this course, tended to be helped more by the open-ended version ofthe lab than students who are generally stronger on this material. This outcome suggests thathaving to design their own experimental protocol may make students more likely to understandor remember all steps involved in particular data reduction tasks.

Themotion of the particle is constrained to have constant velocity and solutions are usually foundusing three classic kinematics equations. The problem description below shows three points ofinterest in the trajectory, A, B, and C. Each point can have specified its position, S, or velocity,V. Since acceleration in projectile motion is constant, only two constant values, the x- and y-components, are necessary to define the acceleration at all points along the trajectory.

You will determine whether it is possible to reliably and accurately use the PFD (the model) to predict the pressure drop in real piping systems (the prototypes).
