    Equilibrium of a Particle in 2D & 3D

    • A particle is in equilibrium when the vector sum of all forces acting on it is zero.
    • The equations of equilibrium ensure that the net force along each axis (x, y, and z) equals zero.
    • The three scalar equations of equilibrium are: ΣFx = 0, ΣFy = 0, and ΣFz = 0.
    • These equations are valid for any point in equilibrium and can be used to solve for up to three unknowns.
    • Free body diagrams are essential for visualizing the forces acting on a particle and applying the equations of equilibrium.

    Examples

    • Example 1: The text provides a scenario involving forces acting on a particle in 2D space with a known angle. The solution involves applying the equations of equilibrium to find the unknown forces.
    • Example 2: This example showcases a scenario with forces acting on a particle in 2D space. The solution involves using the equations of equilibrium to determine the unknown force components.
    • Example 3: This example involves finding the forces acting on a particle in 2D space, where the particle is at equilibrium. The solution involves applying the equations of equilibrium to determine the unknown values.
    • Example 4: This example showcases a scenario in 3D where forces are acting on a particle at equilibrium. The solution involves using the equations of equilibrium in all three dimensions to calculate unknown force components.
    • Example 5: This example focuses on a particle in 3D space experiencing multiple forces. The solution utilizes the equations of equilibrium to determine the unknown force magnitudes and angles.
    • Example 6: This example involves a particle in 2D space subjected to multiple forces. The solution relies on drawing a free body diagram to visualize the forces acting on the particle and using the equations of equilibrium to find unknown forces.
