Torque

AP Physics 1· difficulty 1/5

A 40 N40~\text{N} force is applied perpendicular to a wrench at a distance of 0.25 m0.25~\text{m} from the bolt. What torque is produced?

  • A

    40 N⋅m40~\text{N·m}

  • B

    10 N⋅m10~\text{N·m}

    check_circle
  • C

    160 N⋅m160~\text{N·m}

  • D

    1.6 N⋅m1.6~\text{N·m}

Explanation

τ=rFsin⁡θ=(0.25)(40)(sin⁡90∘)=10 N⋅m\tau = r F \sin\theta = (0.25)(40)(\sin 90^\circ) = 10~\text{N·m}.
