Articulated Vehicle Option

The reconstruction of highway accidents sometimes involves analysis of the collision responses of articulated vehicles ( e.g., tractor trailers and automobiles with trailers). The m-smac program has added the optional capability to include the simulation of the additional degrees of freedom and tires associated with trailers on one or both of the vehicles (The input for the articulated vehicle option are entered on  Cards 2, 3, 20, 21, 22, 23). (Note: that for a m-smac run with only 1 vehicle exercising the trailer option that the vehicle with the trailer must be vehicle number 1)
