It is a ratio obtained by dividing the volume of the hull of the vessel by the volume of a block having the same length, width and height as the vessel's length, beam and depth.
It is used to infer how "streamlined" a vessel is. An oil tanker would normally have a larger block coefficient than a container ship.
No, the coefficient of friction can vary based on the contact surface area and material properties of the block. When the block is standing on its larger (or smaller) end, the contact surface area and the weight distribution changes, which can affect the coefficient of friction.
The block coefficient (CB) is calculated as the ratio of the underwater volume of a ship's hull to the volume of a rectangular block that has the same overall length, breadth, and draft as the ship. The formula for block coefficient is: [ CB = \frac{V_{ship}}{L \times B \times T} ] Where: CB = Block coefficient Vship = Underwater volume of the ship's hull L = Length of the ship B = Breadth of the ship T = Draft of the ship
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.
No, increasing the mass of the block does not directly affect the coefficient of kinetic friction. The coefficient of kinetic friction depends on the nature of the surfaces in contact and does not change with mass.
Airplane or boat
To find the coefficient of dynamic friction, conduct an experiment by placing a block on a flat surface connected to a force sensor. Apply a horizontal force gradually to the block until it starts to slide, and note the force required for motion to begin. Use the formula: coefficient of dynamic friction = (force to start motion) / (weight of the block) to calculate the coefficient. Repeat the experiment multiple times to get an average value.
I think it is arounf 9w/m2k
By boat.
The coefficient of kinetic friction remains constant regardless of the area of contact between the block and the horizontal surface. It is a property of the materials in contact and does not depend on the surface area.
It would depend on the boat and prop. And boat speed is not measured in mph. It is measured in knots.
The starter in a boat is sealed so that it can't ignite an explosion of fumes in the bilge. You could put a boat starter in a car, but it would be very dangerous to put a car starter in a boat.
