FeaturedEngineering estimate

Axle Load Distribution Calculator

rear_axle_load = total_mass × cg_from_front_axle ÷ wheelbase; front_axle_load = total_mass − rear_axle_loadOpen calculator

FeaturedAdvanced

Tyre Remaining Life Calculator

wear_rate = (previous_tread − current_tread) ÷ distance_run × 1000; remaining_km = (current_tread − minimum_tread) ÷ wear_rate × 1000

Open calculator

Tyre Cost per KM Calculator

cost_per_km = tyre_cost ÷ distance_achievedOpen calculator

FeaturedAdvanced

Dual Tyre Mismatch Calculator

mismatch_percent = abs(circumference_a − circumference_b) ÷ max(circumference_a, circumference_b) × 100Open calculator

Fuel Cost per Trip Calculator

fuel_cost = fuel_used × fuel_priceOpen calculator

FeaturedEngineering estimate

Horizontal Tank Partial Fill Calculator

partial_volume = length × (radius² × acos((radius − fill_height)/radius) − (radius − fill_height) × sqrt(2×radius×fill_height − fill_height²))

Open calculator

FeaturedAdvanced

Pipe Pressure Drop Calculator

pressure_drop = friction_factor × (pipe_length÷diameter) × (density × velocity² ÷ 2)Open calculator

FeaturedAdvanced
