2.003J/1.053J Dynamics and Control I Fall 2007 Problem Set 4 Out: Monday, 1 October, 2007 Due: Wednesday, 10 October, 2007 1. Dump truck The bed of a dump truck is hinged at the rear, as shown in the figure below. Initially, the bed is at rest in the fully lowered position and a box of mass m lies at a distance L 0 from the back end of the truck. At time t = 0, the operator starts raising the bed at a constant angular acceleration α . Assume that the surface is frictionless and that the box can be treated as a point mass. Let L denote the instantaneous distance of the mass from the hinge. Note that gravity acts. Find the equation of motion of the mass and find the normal reaction force as a function of time, L or any of its derivatives and any other variables that are given.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
