Chapter 12, Problem 60P

You’re called to testify in a product liability lawsuit. An infant sitting in the portable seat shown in Fig. 12.36 was injured when it fell to the floor. The manufacturer claims the child was too heavy for the seat: the parents claim the seat was defective. Tests show that the seat can safely hold a child if the force $\stackrel{\to }{F}$ of the table on the chair doesn’t exceed 229 N. The seat’s mass is 2.0 kg, the injured child’s is 10 kg, and the center of mass of child and seat was 16 cm from the table edge. In whose favor should the jury rule?
