iBeams Pro vs RPN

Unlike traditional design tools where you have to define nodes and elements to model your structure, iBeams Pro let's you work like you normally do. You sketch out your beam and loads like you would on a design pad, and instantly view shear, moment, deflection and reactions diagrams. It is very easy to modify and view variations, and you can rapidly analyze several beams in a matter of minutes rather than hours, allowing you to finish your designs more rapidly than ever before. The file format is compatible with iBeams Pro for macOS. Features include: • Beam diagrams with multiple loads and supports, and the corresponding shear, moment, deflection, and reaction diagrams • User editable properties • Imperial and S.I. (metric) units • Editable material and section properties (ships with AISC, BS5950, CISC, and AS/NZS databases) • Multiple supports • Multiple loads • Joints and Moment Releases • Annotations • synchronize preferences and property settings between macOS and iOS versions of this application • support for storing documents on Cloud shares

RPN-55 SD is the first photo-realistic simulation for the iPhone of Hewlett-Packard's low-cost alternative to the famous HP-65 programmable scientific calculator. Produced from 1975 through 1977, it was the "Merlin" member of the classic HP calculator series, priced at $395. HP claimed that it featured "(...) more pre-programmed functions than any other scientific pocket calculator in the world." A main feature of the HP-55 was a crystal-controlled 100-hr digital timer with the ability to store times while the timer was running and later recall them. On RPN-55 SD the timer may also act as a 12-hr or 24-hr clock, including date and weekday display. While the simulator works just like the original calculator – except being much faster and having twice the program memory – you can turn on extended features to make it even more enjoyable to use. RPN-55 SD comes complete with original HP programs built in. Features: • Photo-realistic look-and-feel • Vintage mode or Extended mode • Programmable (99 steps), conditional branching • Insert and delete steps with automatic address correction • Delete range of steps • Subroutines (4 levels) • 20 registers, "continuous", with unrestricted store/recall arithmetic • "Live" register view • Program listing view • Program library view • Store and retrieve any number of programs • 100-hr timer supporting 10 split times and 12/24-hr clock mode with date • Swap unit conversions with additional functions, e.g. hyperbolics • Sharing: e-mail, AirDrop, Dropbox, copy, paste, print • 112 programs pre-installed Calculator functions: • Statistics (linear regression, mean, standard deviation, correlation coefficient, x- and y-estimates) • Trigonometric functions (degrees, radians, grads) • Polar/rectangular conversions • Inverse, square root, logarithm, exponential, pi • Storage arithmetic (store and recall) • Percent, absolute, integer, fractional value, round • Factorial • Random number • Unit and hours conversions Details: cuveesoft.ch/rpn55
