MCAT Chemical and Physical Foundations of Biological Systems Flashcards: 4a Equilibrium Torque Rotational Stability

Study 4a Equilibrium Torque Rotational Stability in MCAT Chemical and Physical Foundations of Biological Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Find α\alpha if ∑τ=12 N⋅m\sum\tau=12\,\text{N}\cdot\text{m} acts on an object with I=3.0 kg⋅m2I=3.0\,\text{kg}\cdot\text{m}^2.

ANSWER

α=4.0 rad⋅s−2\alpha=4.0\,\text{rad}\cdot\text{s}^{-2}. Angular acceleration equals net torque divided by moment of inertia, per the rotational second law.
