OK, a car is not the same as a metal beam. Cars do not really even have a frame and a lot of the metal parts have weak points such as bolts or other connectors. Thus would require much less force to pull apart. Also, the components of the car will start breaking at different times, thus less force would be required. Hulk also damaged the car first by hitting it, this would weaken the tensile strength. He also did not just pull it apart, there was some shearing action, torque and such that make the action more complex than described here. it would not take thousands of tons of force to rip a car in half, you could probably do it with a couple transport trucks easily. Even a tank has weak points (such as the turret ring) that would break when the hulk decides to rip the tank apart. His actions in the movie place his strength on the order of 100 or so tons, which is correct when he is not too angry.
