Surface of revolution . If any curve y = f ( x ) rotates about the z - axis , the equation of the surface generated is yé + z2 = ( x ) ] . Thus , if the ellipse ( x2 a ) + ( y2 + 6 % = 1 ( that is , y = ( b + a ) Va ? – x ? ) ...
When the limiting friction is attained , the angle between the total reaction and the normal to the surface is the ... the angle of inclination for which slipping of the body impends is the ANGLE OF REPOSE for the two rubbing surfaces .
Pascal noted that great forces could thus be produced , and that the total press increases in proportion to the surface area . A light press exerted on the water in a small tube inserted in a barrel may burst the barrel .
