PROBLEM: Consequences of the Black Death included a series of religious, social, and economic upheavals, which had profound effects on the course of European history. The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1347 and 1350 with 30% to 65% of the population killed. It reduced world population from an estimated 450 million to between 350 and 375 million. It took 80 and in some areas more than 150 years for Europe's population to recover.

PROBLEM: An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It connects opposite (left / right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness -- its resistance to roll in turns, independent of its spring rate in the vertical direction. The first stabilizer bar patent was awarded to Canadian inventor Stephen Coleman of Fredericton, New Brunswick on April 22, 1919.

SOLUTION:
what is the purpose of rear sway bar
