    What is the solution for the laminar flow problem?

    Problem: Two horses pull a barge from rest in a canal filled with a viscous fluid that provides laminar resistance (FR = –kv). The two horses walk on each side of the canal so that their net force is applied exactly forward. The barge has a mass of 3000 kg and the donkeys pull forward with a...

    How Does Laminar Flow Resistance Affect Barge Movement in a Canal?

    Problem: Two horses pull a barge from rest in a canal filled with a viscous fluid that provides laminar resistance (FR = –kv). The two horses walk on each side of the canal so that their net force is applied exactly forward. The barge has a mass of 3000 kg and the donkeys pull forward with a...

    Why Does Time Remain Constant on Any Chord in Galileo's Circle?

    Why is it that if you have a circle. If you put any rod from the top center of the circle to any other point on the circle (this would be defined as a chord), then why, if the bead starts at the top, is the time required to slide down any chord independent of the particular chord chosen? I...
