Answer :

four section of chassis frame with their merits

image

Channel Section: The channel section is used for making the long members of the frame. It provides a good resistance to bending. It is poor in torsion. This type of section is used in conventional ladder like frames of LMV (e.g. Mahindra Jeep) and HMV (e.g. Truck, Bus etc). Box section: Box section is good for both bending and torsion. The cross member of conventional frame are made of box sections. This type of frame section is used in frames of motorcycles (e.g. Bajaj Pulsar, Boxer etc.)


Tubular sections: Tubular sections provide good resistance to torsion but poor resistance to bending. Now a days, tubular section is used to make complete chassis frame of three wheeler, scooter, motorcycle, matador and pickup van etc


I-Section: I- section is used for making cross members. I-Section has high moment of inertia and stiffness which makes it resistant to bending moments. The web provides resistance against shear forces. These sections are not resistant to torsional loading (twisting) and they shall not use in the cases where torsion is dominant.
