Logar Resist Calc

Logar Resist Calc app integrates five core functions, tailored for engineers, researchers and students, to solve the needs of efficient calculations in complex scenarios:
Logarithm Base Change: supports logarithmic calculations with any base, real-time conversion of common logarithms (lg), natural logarithms (ln) and custom bases, meeting the needs of mathematics, physics and data analysis scenarios.
Total Thrust from the Soil (Highly Cohesive Soils): Based on Coulomb theory and Terzaghi formula, input parameters such as soil internal friction angle, cohesion, retaining wall height, etc., automatically calculate active/passive earth pressure, and adapt to geotechnical engineering design.
R and L in series: Input resistance, inductance and frequency parameters, quickly solve impedance, phase angle, voltage and current distribution, support complex number operations and result visualization, and help circuit design optimization.
Resistance (Parallel): One-click solution of the equivalent resistance of multiple resistors in parallel, automatically generate detailed calculation steps, support step-by-step disassembly of mixed circuits, and improve circuit analysis efficiency.
Wet bulk density: Combines soil moisture content, dry density and other parameters, automatically converts wet bulk density according to ASTM standards, and is suitable for civil engineering material performance evaluation.

Full-scenario formula adaptation, built-in unit conversion and constant table, providing step-by-step calculation process traceability. The interface is simple and intuitive, and the responsive design is adapted to mobile office, allowing professional calculations to be completed efficiently anytime, anywhere.
