Many sheath-screw davits have markings to indicate the maximum angle to which they should be cranked out. If the angle is exceeded，the davit（）.
举一反三
- The maximum angle at which the intact stability curves are valid for ship’s is the angle for（）.
- What is the angle of repose? A: The angle of an inclined rock layer measured from a horizontal line B: The angle of the slip plane from a slide C: The angle of plunge into the interior D: The steepest angle at which a material remains at rest
- The rotation angle of the cross section at the maximum deflection of the beam must be equal to zero. ( )
- For a bar under axial tension, the sections with the maximum normal stress and maximum shear stress are A: the cross section and inclined section with inclined angle 45°, respectively. B: both the cross sections. C: the inclined section with inclined angle 45°and cross section, respectively. D: both the inclined sections with inclined angle 45°.
- The angle to which a floating ship，with a negative initial metacentric height，lies while at rest in still water is the angle of（）.
