Abstract
An automobile rear axle broke at the differential end when the vehicle collided with a tree at about 35 m.p.h. The fracture surfaces exhibit ed features characteristic of both bending impact and torsional overlo ad. It was concluded that the fracture started as a bending impact whe n the frontal collision forced the entire drive system rearward. The f racture was completed by torsional overload when the drive system lock ed and the wheel continued to turn.
