| **centroidcalculator.zip** | 15k | 20-07-19 | | **Centroid Calculator 1.0** Find the coordinates of the centroid/centre of mass/centre of gravity of a two-dimensional complex shape! Simply break down the compound shape into simpler shapes, finding out their areas and respective centroid coordinates. With those smaller areas and centroid coordinates known, the program finds the overall centroid coordinates for the overall shape! This program aims to reduce the burden and likelihood of error when calculating the centroid manually. It works for compound shapes involving blank areas too! Useful for physics, engineering, or any other course involving centroids/centre of mass/centre of gravity. |

| **chemmath.zip** | 1k | 19-02-06 | | **Chemistry Math Helper** This chemistry helper will help you solve equations relating to finding half-life, finding final mass, finding initial mass, and finding elapsed time. I might eventually add a mass defect helper. |

| **dateconv84.zip** | 1k | 16-12-13 | | **Date Conversion v1.00** The program converts a Gregorian calendar date given as year/month/day/hour/min/sec or year/month/decimal day to the Modified Julian Day number ( MJD = JD-2 400 000.5 ) and vice versa. |

| **discap.zip** | 1k | 20-07-06 | | **Capacitor Value Finder** A very simple program that does exactly what it sounds like it does. This program simply has you enter in the three numbers and the letter(s) (i.e. 103K or 3R3K) that are shown on a disc capacitor and the program will find the value of that capacitor. A very simple, easy, and useful program to have. |

| **doppler.zip** | 1k | 16-11-12 | | **Doppler Effect** This program calculates either the perceived new frequency heard by the observer (due to the Doppler Effect) or the original emitted frequency from the source for various situations such as the source moving towards/away from the observer, the observer moving away/towards the source, both the source and observer moving towards each other, and both the observer and source moving away from each other. This program is an extremely fast way to ensure you don't make any stupid mistakes changing the signs of the equation for each situation. Hope you like it! |

| **forcedvibr.zip** | 25k | 18-09-21 | | **Forced Vibrations v1.11** The program finds for the differential equation ( d. e.) of a forced vibration given as m*d2y/dt2 + d*dy/dt + c*y = F0*cos(omega*t) or m*d2y/dt2 + d*dy/dt + c*y = F0*sin(omega*t) or a combination of both the exact solution dependant on preset initial conditions t0, y0(t0), y'0(t0). V1.11: sign error in the combination case fixed. |

| **halflife.zip** | 2k | 17-12-30 | | **HALFLIFE** This does many half life calculations it should help in chemistry and in physics. Enjoy:) |

| **momentscalculator.zip** | 4k | 20-07-19 | | **Moments Calculator** Find the resultant moment acting about an axis of rotation with this program! Simply specify the number of moments, and their respective forces and perpendicular distance from the axis of rotation. Depending on your sign convention, opposite moments should have a negative force. This program aims to reduce the burden and likelihood of error when calculating the moment manually. |
