Solving Systems of Equations Using Mathcad Charles Nippert This set of notes is written to help you learn how to solve simultaneous equations using Mathcad. You will solve a system of 2 simultaneous linear equations using successive approximations or by using the symbolic processor. The methods you will use can be. Common mechanical engineering calculations like: force, moment, work, energy, momentum, vibration, stress, and fatigue are solved and documented showing users how to leverage PTC Mathcad’s wide variety of functionality. While going through the series of worksheets user will be shown how to utilize the following PTC Mathcad functionality.
Homework StatementThe cutting force developed during a particular machining operation is shown in figure (a).Model the system as a SDF with equivalent mass of the cutting head = 25 kg. The damping is linear viscous (ξ = 0.1), and the equivalent spring is nonlinear “hardening” spring of the form k = k1 + k2.x^2, where k1 = 400 kN/m, and k2 = 40 kN/m3. Assume the initial conditions x(0) = 0 andx' (0) = 0.I need to write a computer program in MathCAD, Matlab, or similar to solve this problem.(These two programs are available to me)(a) Draw the analytical model and write the D.E.
Of the motion of the system.(b) Computer printout of the program listing.(c) Computer output of results (t, x, x' )(d) Computer plot for x(t) vs. T(e) Computer plot for x'(t) vs. T(f) Compute the inaccuracies (in the vertical direction) in the surface finish due to the cutting force.2. Homework Equationsm(d^2y/dt^2)+c(dy/dt)+ky=Fo.sin(wt)3. The Attempt at a SolutionThe first real problem I've run into is modeling the non-linear spring.
In MathCAD, when I put k:= 400+40y^2 it's saying y is undefined, which is true, but how should I define it? I'm not given like 0.
Contents.Overview Mathcad, 's engineering calculation solution, is used by engineers and scientists in various disciplines – most often those of mechanical, chemical, electrical, and civil engineering. Originally conceived and written by (of, co-founder of ), Mathcad is now owned by and is generally accepted as the first computer application to automatically compute and check consistency of engineering units such as the (SI), throughout the entire set of calculations. Mathcad today includes some of the capabilities of a, but remains oriented towards ease of use and simultaneous documentation of numerical engineering applications.Mathcad is oriented around a, in which equations and expressions are created and manipulated in the same graphical format in which they are presented - as opposed to authoring in plain text, an approach later adopted by other systems such as and.Mathcad is part of a broader product development system developed by PTC, and often utilized for the many analytical touch points within the systems engineering processes.
It integrates with PTC’s other solutions that aid product development, including,. Its live feature-level integration with Creo Elements/Pro enables Mathcad analytical models to be directly used in driving geometry, and its structural awareness within Windchill allows live calculations to be re-used and re-applied toward multiple design models.Summary of capabilities The Mathcad interface allows users to combine a variety of different elements (mathematics, descriptive text, and supporting imagery) into the form of a worksheet, which is naturally readable. Because the mathematics are core to the program, the math is inherently live, dynamically recalculating as upstream values are altered. This allows for simple manipulation of input variables, assumptions, and expressions, which in turn update in real-time.
