The muscles of the world. Why, after 70 years, a descendant of the Land Rover Series I got an aluminum body again? (part 2)
Computer and aluminum are power!
How to combine the strength and rigidity of the frame with the characteristics of the supporting body? It was here that engineers, along with the good old theoretical mechanics and sopromat, came to the aid of engineers many times over the past three decades, computer power. In fact, why, relying on the results of scientific achievements, with the help of computers, not choose the optimal profile of the power element depending on the expected load? Those calculations, which previously took months, today are done in … one minute. In fact, the mass of the element becomes the boundary condition: it should be as small as possible, but, say, the choice of the metal thickness and such quantities as the polar moment of inertia can be left at the computer.

Awesome rust, insidious step, call a friend: Cadillac Escalade 3 gen with a range of 200,000 km (part 1)
Do I need to visit an official dealer for owners of large luxury SUVs? Recently, we have already answered this question in the affirmative, at least if we are talking about a car of a European luxury brand. But what about the big “American”, because they are all simple in design, unpretentious and seem to not require qualified attention? We found a nine-year-old third-generation Cadillac Escalade, which traveled more than 200,000 km along Moscow roads, went to the “official”, where he had been servicing all this time, picked it up on the lift and asked all the stereotypical questions that accompanied us, simultaneously clarifying that, in In principle, it can happen on such runs at the frame “American”.
