In engineering, a parallel force system is a type of force system where in all forces are oriented along one axis. An example of this is a see saw . The children are applying the two forces at the ends, and the fulcrum in the middle gives the counter force to maintain the see saw in neutral position.
Block on a ramp and corresponding free body diagram of the block.. In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition.
Suppose two forces act on a particle at the origin (the "tails" of the vectors) of Figure 1.Let the lengths of the vectors F 1 and F 2 represent the velocities the two forces could produce in the particle by acting for a given time, and let the direction of each represent the direction in which they act.
The line of action is shown as the vertical dotted line. It extends in both directions relative to the force vector, but is most useful where it defines the moment arm. In physics , the line of action (also called line of application ) of a force ( F → ) is a geometric representation of how the force is applied.
A bubble chart is a type of chart where each plotted entity is defined in terms of three distinct numeric parameters. The first two parameters are reflected in the chart as the horizontal and vertical coordinates of the center of each plotted "disc", as in a typical scatter plot, while the third determines the size of each disc. Bubble charts ...
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
When most lines between two parallel axes are somewhat parallel to each other, it suggests a positive relationship between these two dimensions. When lines cross in a kind of superposition of X-shapes, it's a negative relationship. When lines cross randomly or are parallel, it shows there is no particular relationship.
Vertical – spanning the height of a body. Longitudinal – spanning the length of a body. Lateral – spanning the width of a body. The distinction between width and length may be unclear out of context. Adjacent – next to; Lineal – following along a given path. The shape of the path is not necessarily straight (compare to linear).
