  2. Tractive effort - Wikipedia

    en.wikipedia.org/wiki/Tractive_effort

    The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...

  3. Forces on sails - Wikipedia

    en.wikipedia.org/wiki/Forces_on_sails

    Each sailing craft is a system that mobilizes wind force through its sails—supported by spars and rigging—which provide motive power and reactive force from the underbody of a sailboat—including the keel, centerboard, rudder or other underwater foils—or the running gear of an ice boat or land craft, which allows it to be kept on a course.

  4. Drag equation - Wikipedia

    en.wikipedia.org/wiki/Drag_equation

    is the drag coefficient – a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag. If the fluid is a liquid, c d {\displaystyle c_{\rm {d}}} depends on the Reynolds number ; if the fluid is a gas, c d {\displaystyle c_{\rm {d}}} depends on both the Reynolds number and the Mach number .

  5. Drag curve - Wikipedia

    en.wikipedia.org/wiki/Drag_curve

    The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.

  6. Traction motor - Wikipedia

    en.wikipedia.org/wiki/Traction_motor

    It is now standard practice to provide one traction motor driving each axle through a gear drive. Nose-suspended DC traction motor for a Czech ČD class 182 locomotive. Usually, the traction motor is three-point suspended between the bogie frame and the driven axle; this is referred to as a "nose-suspended traction motor".

  7. Automobile drag coefficient - Wikipedia

    en.wikipedia.org/wiki/Automobile_drag_coefficient

    Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...

  8. Drag coefficient - Wikipedia

    en.wikipedia.org/wiki/Drag_coefficient

    Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.

  9. Drag count - Wikipedia

    en.wikipedia.org/wiki/Drag_count

    A drag count is a dimensionless unit used by aerospace engineers. 1 drag count is equal to a of 0.0001. [ 1 ] [ 2 ] As the drag forces present on automotive vehicles are smaller than for aircraft, 1 drag count is commonly referred to as 0.0001 of C d {\displaystyle C_{d}} .
