When the force acting on the end of the lever has made one revolution, the weight which rests upon the top of the screw has evidently been lifted through a vertical distance equal to the distance between the threads. Has the hand which furnishes the power moved much farther than the weight has been lifted? For what purposes are jackscrews used ? The most common example of a screw is the bolt and nut. Why is a wrench used in turning a nut on a bolt ? The screw press and the vise...
Page 107 - If the cohesive force oF(Fig. 117) is strong in comparison with the adhesive force oE, the resultant oR will fall to the right of the vertical, in which case the liquid must be depressed about o. Whether, then, a liquid will rise against a solid wall or be depressed by it, will depend only on the relative strengths of the adhesion of the wall for the liquid and the cohesion of the liquid for itself.
