The Price Floor is a minimum price set for selling items on ROBLOX, which was introduced on September 24, 2013. Along with the Outlines update, the price floor update was heavily criticized by the community upon its release. Prior to this update, the minimum price of T-shirts, Shirts and Pants was 1 and 5.
This system was first introduced in the CitroÃ«n SM in 1970, and was known as 'VariPower' in the UK and 'SpeedFeel' in the U.S. In the late 1960s, General Motors offered a variable-ratio power steering system as an option on Pontiac and other vehicles.
In a power steering system, movements made on the steering wheel cause fluid pressure inside the hydraulic pump to move to one side or the other of the pump. This pressure causes a piston to move, and that piston directs the gears to steer the car.
