|Plan view of ladder frame|
A ladder frame is welded of 2"-by-4", 16 gauge steel. It is composed of two longitudinal members, approximately 36" apart. All members are in the same plane and all sectionss are in "portrait" orientation.
The first cross piece from the left is to stabilize the longitudinal members as they crush. The second, third, fourth and fifth cross pieces are for seat attachment.
- The buggy is now stuck to the front of the bullet vehicle and both are moving 26 miles per hour. The mass of the buggy slightly slowed the bullet vehicle
- 12-to-24 inches of the longitudinal members crushed in an accordion-pleat fashion.
- None of the passengers experienced fatal trauma unless they weighed less than fifty pounds and were not in a protective, child seat.
- The seats are in the full rearward position but will flop forward as soon as the frame starts to decel
- On decel, the occupants will fly forward, out of their seats unless they have some kind of restraint.
- The front of the frame is lifting upward
- The front of the frame is about to impact the rear of the 1000 pound horse at 26mph. That impact will further slow the assembly to 23mph.
