Question

After changing a tire on your car, you need to tighten one of the lug nuts to the proper specified torque of 24.0 Nm. How much force is needed if you're pushing down on the end of the 34.0 cm long torque wrench at an angle of 120° with respect to the wrench shaft? O 81.5 N 70.6 N 0 141 N O 7.07 N Question 3 A baseball, with radius 3.20 cm and mass 0.260 kg, is rolling along the floor at 3.50 m/s when it comes to a ramp inclined at 20.0°. How far up the ramp will the baseball roll before stopping? 2.56 m o 9.31 m O 1.46 m O 1.83 m

Answer 1

Torque is defined as the product of perpendicular component of force and the length of the lever arm. Mathematically written as, T = Frsin Solve the equation for F. T=Frsin rsin 24.0 Nm (0.34 m) sin 120° = 81.5N
