the shape of the head is depended upon the purpose for which bolt is required. the nut is a type of a fastener which has a threaded hole in it. the nut is always used in joining with a mating bolt to fasten various parts together. types of nuts and bolts. different forms and types of nuts and bolts are as follows: form of bolts. hexagonal-headed bolt
engineering discoveries. track ballast is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials, for example burnt clay. the term “ballast” comes from a nautical term for the stones used to stabilize a ship. track ballast forms the track bed upon which railroad ties (sleepers) are laid.

in an electric power system, a fault or fault current is any abnormal electric current. for example, a short circuit is a fault in which current bypasses the normal load. an open-circuit fault occurs if a circuit is interrupted by some failure. in three-phase systems, a fault may involve one or more phases and ground, or may occur only between phases. in a 'ground fault' or 'earth fault', current flows into the earth. the
although substation / switchyard grounding is very low in the range of 0.5 to 5 ohm to provide low resistance path, the entire ground is filled with gravels to provide a high resistance layer so that it can act as an insulation between our foot and the ground. the layers of gravels on the substation/ switchyard surface provide high resistance so
