To the elevating screw' is 3 feet, and the distance of the centre of gravity of the gun from the same axis is 4 inches. If the distance between the threads of the screw be | of an inch, and the length of the lever 5 inches, what power must be applied to sus- tain the gun in a horizontal position ? Ans. 4. 754 lbs. The Wedge. 87. The wedge is a combination of two inclined planes. It is bounded by a rectangle, BD, called the back; two rectangles, AF and DF, called faces ; and two isosceles triang...les, called ends. The line, FF, in which the faces meet, is the edge. The power is applied at the back, to which it should be normal, and the resistance is applied to the faces, and normal to them. One half the resistance is applied to one face, and the other half to the other face. Let ABC he a section of a wedge by a plane F te- si. At right angles to the edge. Denote the power by P, the re- sistance opposed to each face by $B, and the angle B A C by 2
