1. The problem statement, all variables and given/known data A refrigerator is approximately a uniform parallelepiped h = 8 ft tall, w = 3 ft wide, and d = 2 ft deep. It sits upright on a truck with its 3 ft dimension in the direction of travel. Assume that the refrigerator cannot slide on the truck and that its mass is 130 kg. For the first three parts of this problem, the rope shown in the picture is not there. c) What is the maximum acceleration the truck can have such that the refrigerator does not tip over? d) Suppose now that a rope connects the top of the refrigerator with the cab of the truck, which now accelerates at twice the acceleration calculated in (c). The refrigerator lifts off slightly at the front but is held in place by the horizontal rope. Find the tension in the rope. 2. Relevant equations F=ma T=Ia T-rFsin(theta) 3. The attempt at a solution So I guess that the frig is just starting to tip, so only the back corner is touching. That's the pivot point then, but I'm lost about the forces and where they are acting I know gravity acts on the center of mass, a normal force on the contact point, but there must be more.
