A mechanic jacks up a car to an angle of 8 degress to change the front tires. The car is 3.05 m long and has a mass of 1130 kg. Its center of mass is located 1.12 m from the front end. The rear wheels are .4 m from the back end. Calculate the torque exerted by the car around the back weels. The answer is 1.68 times 10 to the 4 But i can't figure out how to get the to the answer. I'm not sure where i can put the pivot point... the distance of the jack is unavailable. this problem is keeping me from doing any other problems...help.
