MCAT Physics and Math 1.7: Mechanical Equilibrium

  • Dynamics

    The study of forces and torques

  • Free body diagram

    A free body diagram consists of a diagrammatic representation of a single body or a subsystem of bodies isolated from its surroundings showing all the forces acting on it.

    A free body diagram consists of a diagrammatic representation of a single body or a subsystem of bodies isolated from its surroundings showing all the forces acting on it.

  • Translational motion occurs when _____.

    forces cause an object to move without any rotation

  • Translational equilibrium exists only when the _____.

    vector sum of all of the forces acting on an object is zero.

    (this is the second condition of equilibrium)

  • When dealing w/ mechanics, always _____.

    draw out the free body diagrams!

  • Rotational motion occurs when forces are applied against an object in such a way as to cause the object to _____, also known as the _____.

    rotate around a fixed pivot point

    fulcrum

  • Formula for torque

    τ = r × F = rF sinθ

    ...where r is the length of the lever arm, F is the magnitude of the force, and θ is the angle between the lever arm and force vectors

  • Rotational equilibrium exists only when the _____.

    vector sum of all the torques acting on an object is zero.

    (this is the second condition of equilibrium)

  • Torques that generate clockwise rotation are considered _____, while torques that generate counterclockwise rotation are _____.

    negative

    positive

  • _____ is the angular equivalent of _____.

    torque (τ)

    force (F)
