17. 590 Assumptions: 1.The pressure at any point on the shoe is proportional to the distance from the hinge pin, being zero at the hill. 2.The effect of the centrifugal force is neglected. 3.The shoe is rigid. 4.The friction coefficient does not vary with pressure.

18. 591 Infinitesimal rotation deformation

19. 592 Interesting and useful characteristics: 1.The pressure distribution is sinusoidal with respect to angle. 2.If the shoe is short, the largest pressure on the shoe is pa occurring at the end of the shore. 3.If the shoe is long, the largest pressure on the shoe is pa occurring at the 90 o.
