A mechanic jacks up the front of a car to an angle of 8.0° with the horizontal in order to
change the front tires. The car is 3.05 m long and has a mass of 1130 kg. Gravitational force
acts at the center of mass, which is located 1.12 m from the front end. The rear wheels are
0.40 m from the back end. Calculate the magnitude of the torque exerted by the jack.
