    2012-10-15 · 4 Analysis of the Heavy Ball Method We restrict our attention to the case where k and k are fixed constants. To prove this method converges, we use a time-lagged version of the standard Lyapunov function. That is, instead of looking at kx k+1 x k2, we examine kx k+1 x k2 + kx k x k2. For this invariant, we have the chain of inequalities x k+1 x x k x = x k rf(x k) + (x

  • Types of Bearings - How Bearings Work |

    In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly.But it also means that there is not very much contact area holding that load, so if the bearing is overloaded, the balls can deform or squish, ruining the ...
