For the roller coaster seat described in Prob. 4.92, determine a wrench equivalent force system and specify the x and z coordinates of the point where the wrench's line of action intersects the xz plane.
Prob. 4.92
A seat of a roller coaster is subjected to the forces shown during a turn. The force at A is vertical, the forces at B and C are parallel to the x and z directions, respectively, and the forces at D and E lie in planes parallel to the yz plane. Determine an equivalent force system at point O, where the seat is attached to the car.
