Truly an Endurance test!!


Surely this situation would not have been considered during the vehicle's design. Approximately taking each person to be 50 kg, and I see atleast 25 people standing on the top, it amounts to more than a tonne. I am sure the roof was designed to offer only structual stability and not to bear loads. AL has the right to be proud!!

ha ha! Losers!!
ok now AL design goes like this....
for a 12 tonne load vehicle (dead + pay), use 11m chasis with frame gauge thickness 8mm.(since BL days :D)
I bet 5.5 - 6 would still maintain a FOS of 2.0, but these guys use atleast 3.0**.. now in the market they say, if u buy an AL vehicle with marked max load of N tonne, it can take 2N tonne***, then...(no comments :P).. now go and check the dead weight to laden weight ratio (specification wise), and compare it with TATA(*).

not the least, AL can always go to a layman and say their products are superior....
but still, they dont build the body! :P, so ur claim doesnt make sense here

loosa...all said and done, u r only talking about frame design and cross bearers...adhoda loads elaam directly transferred to suspension-->axle-->wheels...
but roof is just a sheet metal work with cross supports for rigidity and forms no part of a load bearing structure...and AL has body building facility in pondicherry from which these MTC buses come....
anyways..one imp matter..u left out a major reference: ultimate expert in failure analysis and endurance testing. Prof Bhaskar.
have u forgotten the way he proposed a new theory to test one composite structure?
