Description
Summary:10.1119/10.0005889.1 The toppling motion of a uniform rectangular block is investigated as a function of the friction between its pivot edge and the horizontal surface on which it rests. Initially, the edge of the block remains stationary, but it inevitably slips before the block lands. The inclination angle at which slipping occurs and the direction of slip depend on the coefficient of static friction. The toppling motion of a granite block was monitored at 400 Hz with MEMs gyro/accelerometers at the center of mass and at the pivot edge, as well as by “Tracker” analysis of video recorded at 240 fps.
