Sen. Joe Biden wanted a sweetheart deal for the banks that stripped student loans of bankruptcy protections, and it created a train wreck. //

In general, borrowers burdened by too much debt and unable to pay their loans can usually discharge them in a personal bankruptcy case. Some debts, particularly those owed to the government, are not dischargeable. But consumer loans and credit card debts generally are dischargeable. //

Why did Biden staunchly back this change — even as Democrats like Teddy Kennedy denounced it for “sacrific[ing] Americans to the rampant greed of the credit card industry”? Because Biden was a long-time water carrier for the credit card and banking industries. And both he and his family profited from that arrangement.

Il reste maintenant la question qui nous a amené ici : que se passe-t-il si on roule à 110km/h au lieu de 130km/h ? Cela correspond à une diminution de seulement 15% de la vitesse.

Mais on voit que pour les frottements aérodynamiques (la source principale de consommation), ce qui compte c’est le carré de la vitesse ! En utilisant une vitesse de 110km/h, on trouve une valeur de 42 MJ (au lieu de 60) pour le travail de cette force. Notre total de 72 MJ se trouve donc réduit à 54 MJ, soit une diminution de 25% de la dépense énergétique.

On voit donc que du fait que les frottements aérodynamiques (80% du total) dépendent du carré de la vitesse, une diminution de vitesse de 15% engendre une diminution de consommation de 25%. Évidemment, il faudrait un peu raffiner en regardant la façon dont le rendement du moteur dépend de l’allure, etc., mais une fois de plus ça donne l’ordre de grandeur qui nous permet de raisonner quantitativement.
