Parallel forces have various applications in engineering and physics, particularly in the analysis of structures and mechanics. They are essential in understanding the behavior of beams and bridges under load, where forces act in the same direction, affecting stability and design. Additionally, parallel forces are used in systems like cranes and hoists, enabling efficient lifting and movement of heavy objects. Their principles also apply in everyday situations, such as in the operation of levers and pulleys.
Math allows you to calculate load, forces, stability, fragility, stress, strain, it goes on for ever.

The polygon method is most suitable graphical technique for analyzing concurrent forces because it allows for the graphical addition of multiple vectors without the need any complex calculations. This method is particularly useful when dealing with systems of forces acting at a single point or in a plane. By using the polygon method, can visually determine the resultant of multiple forces, which simplifies the analysis and helps in understanding the overall effect of the forces on a system
It can be both. Negative if the organization does not keep up with advancements in technology, a positive if it does. This is one reason why organizations must collect, analyze, and act on all internal and external environmental forces.
