This application models the trajectory of a bullet fired from a gun. Specifically, the application numerically solves the differential equations that describe the motion of the bullet (assuming three degrees of freedom), together with a correlation for air resistance. The predictions are compared to manufacturer-supplied velocity-range data for a specific type of bullet; the model closely matches the manufacturer's data.<img src="https://www.maplesoft.com/view.aspx?si=154651/thumb2.png" alt="Trajectory of a Bullet Using an Air Resistance Correlation" style="max-width: 25%;" align="left"/>This application models the trajectory of a bullet fired from a gun.

https://www.maplesoft.com/applications/view.aspx?SID=154598&ref=Feed
The following is a detailed study of the motion of an unconventional Atwood Machine where one mass is constrained to move along a fixed vertical axis.
The differences with the regular Atwood Machine are :
1- the tension T on the string on either side of the pulley though it is the same, however it is not constant in the present case because of the obliquity of the 2d part of the string.
2- the unique and constant acceleration (a) in the simple machine is replaced in here with two different and variable accelerations whose ratio is however constant.
3- In the simple machine the constant acceleration makes plotting and animation of the system a straightforward procedure according to
s = (1/2)*at^2.However in the modified Atwood machine that we present in here the accelerations being variable there is no way to get the displacement as a direct function of time. This seems to make plotting & animation an impossible task. However we were able to devise a trick to overcome this difficulty.<img src="https://www.maplesoft.com/view.aspx?si=154598/Modified_Atwood_Machine.jpg" alt="Atwood Machine" style="max-width: 25%;" align="left"/>The following is a detailed study of the motion of an unconventional Atwood Machine where one mass is constrained to move along a fixed vertical axis.

https://www.maplesoft.com/applications/view.aspx?SID=154000&ref=Feed
The design optimization of helical springs is of considerable engineering interest, and demands strong solvers. While the number of constraints is small, the coil and wire diameters are raised to higher powers; this makes the optimization difficult for gradient-based solvers working in standard floating-point precision; a larger number of working digits is needed.
<BR><BR>
Maple lets you increase the number of digits used in calculations; hence numerically difficult problems, like this, can be solved.
<BR><BR>
This application minimizes the mass of a helical spring. The constraints include the minimum deflection, the minimum surge wave frequency, the maximum stress, and a loading condition.
<BR><BR>
The design variables are the diameter of the wire, the outside diameter of the spring, and the number of coils.<img src="https://www.maplesoft.com/view.aspx?si=154000/helical_spring.png" alt="Optimizing the Design of a Helical Spring" style="max-width: 25%;" align="left"/>The design optimization of helical springs is of considerable engineering interest, and demands strong solvers.
