31. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them. 32. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations , but not parallel to them. 33. The 10030 subseries featured a new lightweight stainless steel body design, with a reduced number of bodyside corrugations and dull finish. 34. The simulation includes a regular sinusoidal corrugation of the circular shape of amplitude 10 �m, 50 �m and 100 �m, respectively. 35. Random edge corrugation whose amplitude is of the same order as the width of that adjacent Fresnel zone reduces the Arago spot intensity. 36. Corrugated fiberboard has a higher stiffness ( resistance to bending ) than flat fiberboard of equal mass, especially parallel to the corrugations . 37. For increased protection against mines, the sides of the hull floor are sloped by 45?and the floor is reinforced with corrugations . 38. Another problem with gravel roads is washboarding the formation of corrugations across the surface at right angles to the direction of travel. 39. Slowly moving vehicles stress the road over a longer period of time, increasing ruts, cracking, and corrugations in the asphalt pavement. 40. The access road is under regular criticism from patrons because of its corrugations , steep incline with tight switchbacks and lack of safety barriers.
