Torque

AP Physics 1· difficulty 1/5

A 30 N30~\text{N} force is applied perpendicular to a 0.40 m0.40~\text{m} wrench. What torque results?

  • A

    120 N⋅m120~\text{N·m}

  • B

    30 N⋅m30~\text{N·m}

  • C

    7.5 N⋅m7.5~\text{N·m}

  • D

    12 N⋅m12~\text{N·m}

Explanation

τ=rF=(0.40)(30)=12 N⋅m\tau = r F = (0.40)(30) = 12~\text{N·m}.
