Physics Problem. The question is “With what force must you pull”?

NetherCraft 0

The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 49 N⋅m . You plan to tighten the plugs by pulling on the end of a 28-cm-long wrench. Because of the cramped space under the hood, you’ll need to pull at an angle of 105 ∘ with respect to the wrench shaft.

  • 49 = 28*F*sin 75

    F = 49/(0.28*0.966) = 181.16 N
