Abstract:
A method for controlling pressure applied to a displaceable piston in a cylinder, piston displacement actuating a control element of an automatic transmission during a gearshift, includes determining whether piston displacement exceeds a free length of an isolation spring located between the piston and a friction plate of the control element; calculating the pressure using A the cross-sectional area of the piston; K a coefficient of a return spring extending between the piston and a reference position in the cylinder; x the piston displacement; Fa pre-load of the return spring; xthe free length of the isolation spring; and Ka coefficient of the isolation spring; and applying the calculated pressure to the piston.
Prominent art writers and critics, including Sarah Thornton, Felix Salmon, Will Gompertz and Dave Hickey, have been attacking the art world, arguing that the staggering sums of money being spent on works are distorting judgments about art and undermining its long-term cultural significance.
