Question

The shapes of automobile narrows towards front. give reason

Answer 1

There are basically several types of frames used for automobiles.The type of frame which is narrow at the front is known as Ladder Frame.



So named for its resemblance to a ladder, the ladder frame is one of the simplest and oldest of all designs. It consists of two symmetrical beams, rails, or channels running the length of the vehicle, and several transverse cross-members connecting them. Originally seen on almost all vehicles, the ladder frame was gradually phased out on cars in favor of perimeter frames and unitized body construction. It is now seen mainly on trucks. This design offers good beam resistance because of its continuous rails from front to rear, but poor resistance to torsion or warping if simple, perpendicular cross-members are used. Also, the vehicle's overall height will be greater due to the floor pansitting above the frame instead of inside it.
