The hand axe, made by chipping flint to form a wedge, in the hands of a human transforms force and movement of the tool into a transverse splitting forces and movement of the workpiece.The hand axe is the first example of a wedge, the oldest of the six classic simple machines, from which most machines are based.The second oldest simple machine was the inclined plane Advantages of providing a transition curve at each end of a circular curve: (i) The transition from the tangent to the circular curve and from the circular curve to the tangent is made gradual. A traverse is said to be closed traverse when the traverse formed a closed circuit as shown in the figure. (viii) Set the vernier to a reading(360-2/3 1 ) for a right-hand curve (or 2/3 1) for a left-hand curve and lake a back sight on T. Loosen the upper clamp and turn the telescope clockwise through an angle 2/3 1 the telescope is thus directed towards common tangent at E and the vernier reads 360.

Definition of Curves: Curves are regular bends provided in the lines of communication like roads, railways etc. The points on the combined curve should be pegged out with through change so that there will be sub-chords at each end of the transition curve and of the circular curve. (iv) Set up a theodolite at T, set the vernier A to zero and bisect B. A reverse or serpentine curve is made up of two arcs having equal or different radii bending in opposite directions with a common tangent at their junction.
