## What is DorviTank?

Two desks for tasks that are usually calculated on paper: towing a cart on a slope and sizing keyboard strings.

On the slope table, you set the steepness of the slope, the length of the slope, the equipment and the traction rope, and load the passengers into the ascending and descending carriage. Since the carriages balance each other on the same rope, the table returns the unbalance force, resistance, pull on the drum, rope safety factor, drum torque, engine power, brake torque, driving time, shift interval and passengers per hour.

On the string table, you choose the pitch, the lowest note, the frequency of the A note, the ringing length and the thickness of the string. It solves the equation of a vibrating string one note at a time and returns the tension of each string, the strain against the breaking point of the string, the downward force on the soundboard, the length of the body required and the wobble rates of your tuning.

In the application:
• Numbers are recalculated for each change
• Sizing curve and full language-specific table
• A driving log that stores the numbers and their starting values
• Metric or inch measurement and adjustable precision
• Reference notes for each formula used
