Wired White v1 Estimate bicycle chain links, check derailleur capacity, and compare gear inches, development and speed. Includes single-speed adjustment and a wrapped-chain schematic.
Drivetrains and mechanisms
Wired White v1 
Engine Compression Ratio Calculator, Displacement and Boost
Wired White v1 Calculate displacement, static and dynamic compression ratios, and a boost comparison index. Explore gasket and head-milling changes with an animated cylinder section.
Flange Bolt Circle: PCD Hole Positions and Chord Spacing
Wired White v1 Calculate bolt circle hole coordinates and adjacent chord spacing from PCD, hole count and start orientation. Includes a numbered flange drawing, centre offsets and clockwise or counterclockwise numbering.
V-Belt & Pulley Calculator: RPM, Length, Wrap and Power
Wired White v1 Calculate pulley ratio and RPM, belt length, adjusted centre distance, wrap, belt count and static shaft pull. Compare fan performance after a pulley change.
Lathe and Mill Speeds and Feeds Calculator: RPM and Power
Wired White v1 Calculate lathe or mill RPM, feed, metal removal, cutting power and torque. Compare machine limits using HSS/carbide starting speeds and chip-thickness-corrected cutting force.
Hydraulic Power Unit: Pump Flow, Motor kW, Cylinder Force and Speed
Wired White v1 Size a hydraulic power pack from pump displacement, pressure and cylinder geometry. Calculate push/pull force, speed, motor demand, reservoir volume, cooling duty and rod buckling.
Ball Bearing Number Decoder, L10 Life and Load Calculator
Wired White v1 Decode bearing numbers, bore sizes and suffixes. Calculate equivalent load, L10 life and the dynamic rating needed for a target life using your maker’s C rating.
Horsepower vs Torque Calculator: Gearing and Wheel Force
Wired White v1 Explore hp vs torque with editable dyno points, six-speed gearing, wheel force and road loads. Compare a high-torque engine with a high-revving engine at the same speed.
Four-Bar Linkage Calculator and Coupler Curve Analyzer
Wired White v1 Analyze Grashof type, link positions, velocities, accelerations, and transmission angle. Animate either assembly branch and trace a coupler curve.
Compression Spring Calculator & Designer
Wired White v1 Design a round-wire compression spring: calculate rate, solid height, Wahl stress, buckling, Goodman fatigue and surge frequency, with animated compression.
CNC Router Feeds and Speeds Calculator with Tool Deflection
Wired White v1 Calculate chip load, radial chip thinning, feed rate, spindle power and static end mill deflection. Explore cutter engagement and the effect of stickout.
Quarter Mile Calculator and 0–60 Simulator
Wired White v1 Simulate quarter-mile ET, trap speed and 0–60 mph from an engine torque curve, gearing, shift delays, tire grip and road loads. Replay the pass and compare the forces.
Gear Ratio and Involute Gear Calculator
Wired White v1 Calculate gear-train ratio, speed and torque; inspect a rotating involute spur pair with profile shift and contact ratio, then compare road speed by gear.
Tire Size, Speedometer and Gearing Calculator
Wired White v1 Compare tire sizes, speedometer error and engine RPM in every gear. Find regear targets and see how wheel offset changes a measured clearance envelope.
Tolerance Stack-Up Calculator: Worst Case, RSS & Monte Carlo
Wired White v1 Analyze a signed 1D dimension chain with worst-case limits, RSS and seeded Monte Carlo. Compare assembly yield and identify the tolerances that dominate variation.
Shaft Diameter Calculator: Torque, Bending, Fatigue & Critical Speed
Wired White v1 Size a solid steel shaft for torque, bending and infinite-life fatigue. Check bearing loads, deflection, slope and Rayleigh critical speed, with diagrams and a rotating stress-cycle animation.
