The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 43 Nm. You plan to tighten the plugs by pulling on the end of a 27-cm-long wrench. Because of the cramped space under the hood, you'll need to pull at an angle
120Вє means if is off perpendicular by 30Вє. That means the force perpendicular to the shaft is Fcos30
That times the length is the torque, and this is 0.27(Fcos30) and it should equal 43 Nm
0.27(Fcos30) = 43
F cos 30 = 159
