E-CodeTI-89 Titanium engineering programs
10 checked engineering programs for the TI-89 Titanium. Each one runs in E-Code's virtual calculator in your browser, and you can put it on your own calculator.
The programs
- RLC resonance, Q, bandwidth and impedance: Series or parallel RLC (drop-down): resonant frequency, quality factor, bandwidth, and the impedance magnitude and phase at any frequency — each formula is one of your own Define'd functions.
- Beam reactions, shear and moment for a point load: A simply supported beam with one point load P at a from support A: both support reactions, the largest shear and the largest bending moment and where it is.
- Propped cantilever by double integration, step by step: A beam fixed at A and on a roller at B, with a uniform load w and a point load P.
- Series RLC step response, step by step: A series RLC circuit switched onto a DC voltage from rest.
- Principal stresses in 3D, step by step: A full 3D stress state (three normal and three shear stresses).
- Two-mass vibration: natural frequencies and mode shapes, step by step: Two masses on three springs (wall, between the masses, wall).
- Pratt truss by the method of sections, step by step: A Pratt bridge truss with n panels, equal loads at the bottom joints and supports at both ends.
- Mohr's circle and plane-stress transformation, step by step: σx, σy, τxy and a plane angle θ.
- Shaft diameter for bending and torsion, step by step: A solid round shaft with a bending moment M and a torque T, a yield strength Sy and a safety factor n.
- Heat exchanger by ε-NTU, checked with LMTD, step by step: Inlet temperatures, the two capacity rates and UA, counterflow or parallel flow.
