In Fig. E5.10 the weight $w$ is 60.0 $\mathrm{N}$ . (a) What is the ten-sion in the diagonal string? (b) Find the magnitudes of the horizontal forces $\vec{F}_{1}$ and $\vec{F}_{2}$ that must be applied to hold the system in the
position shown.

Key Concepts

Static Equilibrium

This concept involves a system where all forces and torques balance out, resulting in no net acceleration. In such cases, the sum of the forces in every direction (typically horizontal and vertical) must equal zero. This principle is essential for determining unknown forces in structures and mechanical systems at rest.

Force Decomposition

Force decomposition is the process of breaking a force into components along specified axes, usually horizontal and vertical directions. This technique, often using sine and cosine functions, is crucial when analyzing forces that are applied at an angle, allowing the resolution of complex force interactions into simpler, manageable parts.

Tension in Strings

Tension refers to the force conducted along a string or rope when it is pulled tight by forces acting from either end. Understanding tension is fundamental in solving problems related to suspended objects and systems where the force is transmitted along non-horizontal paths, especially when the string is oriented at an angle.

Free-Body Diagrams

A free-body diagram is a graphical illustration used to visualize the forces acting on a single object. By representing all external forces, including weight, tension, and applied forces, it helps in setting up the equations necessary for applying static equilibrium conditions and solving for unknown variables.
