The space diagram takes care of the point of application of forces and the geometry of the truss. The above shown figure is only to get the reactions. Applied force is ab and force is bc in the vector diagram. Reaction is equal to da and Reaction is equal to cd in the vector diagram.

A closed vector diagram is a set of vectors drawn on the Cartesian using the tail-to-head method and that has a resultant with a magnitude of zero. This means that if the first vector starts at the origin the last vector drawn must end at the origin.

If two vectors are perpendicular to each other, then their dot product is equal to zero.

A drawing of a structure that indicates its form as well as means of its support and loading conditions.

a graphical method of finding the reactive forces and resultants of a system of forces, constructing bending-moment diagrams, determining the rational shapes of arched and suspended systems, and solving other problems of the statics of two-dimensional systems.

The probability space is the set of all possible outcomes. It can sometimes simplify our work if you draw a possibility diagram to show all outcomes clearly.

1. • – Draw horizontal and vertical axes.
2. Space coordinate observer 1. T.
3. • – Draw a timelike line.
4. Space coordinate observer 1. T.
5. W. orld.
6. • – A point on the spacetime diagram is called an event.
7. Possition of Event A. according to observer 1.
8. – Take a line from the event, parallel to the space axis of observer 2.

The time-space diagram is a chart that plots ideal vehicle platoon trajectories through a series of signalized intersections. The locations of intersections are shown on the distance axis, and vehicles travel in both directions (in a two-way street).

A coordinate system is a way of representing space and time using numbers to represent points. We assign a set of three numbers, (x,y,z), to characterize points in space, and one number, t, to characterize a point in time. Combining these, we have general space-time coordinates: (x,y,z,t).

in the theory of relativity, a quantity that characterizes the relation between the spatial distance and the time interval that separate two events. From the mathematical standpoint it is the “distance” between two events in four-dimensional space-time.

Moving through space necessitates you to move through time as well. Hence, they argue that time is the 4th dimension since without it, we cannot construct any meaningful position vector with an unchanging length. Time’s dimension is a line going from the past to present to future.
