The Helical Sweep option is used to create helical swept features. You have to define a trajectory that will revolve along an axis, a pitch value, and a cross-section to create a helical feature using this option. The distance of the trajectory from the center line defines the radius of the helical path and the length of the trajectory defines the length of the swept feature. The main use of this option is to create the helical springs and threads. When you choose the Helical Sweep option from the Insert menu in the menu bar or when you choose the Helical Swp option from the ADV FEAT OPT submenu and choose Done Constant The Constant option is used to create a helical feature with constant pitch Variable The Variable option is used to create a helical feature of varying pitch. While using this option you have to define the start pitch and the end pitch, you can also define a pitch between the start and the end point of the helix. Thru Axis

Casting is a process in which molten metal flows by gravity or other forces into a mold where it solidifies in the shape of mold cavity. The term casting is also applied to the part made by this process Metal casting processes divide into two main categories, based on the mold type • Permanent mold casting process • Expandable mold casting process Permanent mold casting In permanent mold casting, the mold is reused many times. Uses a metal mold constructed of two sections designed for easy, precise opening and closing. Molds used for casting lower melting point alloys are commonly made of steel or cast iron. Molds used for casting steel must be made of refractory material, due to the very high pouring temperatures. Permanent mold casting has nine basic types  1. Slush Casting  Slush casting is a variation of permanent mold casting that is used to produce hollow parts in manufacturing industries .It is one of the most important process use in manufac

We did not name the device seen above as we did not know the name of this device we have find this picture in a book which contain pictures of some old mechanical devices, usually when the electricity was not invented yet. That's why this device does not need electricity to perform its work. If any of you know the name please tell us by commenting or by contact form About The Device   Two ladles are made from copper, the capacity of the scoop of each ladle a known quantity of water, more or less. Let the handle of each ladle be channel discharging into the scoop. The ends of the handles are brought together at a right angle and soldered firmly together. Crosswise inside the angle is an axle whose ends, resting in firm support, move in bearing. The centre of the axle is soldered firmly inside the angle.  The axle is marked a , the two scoops y and m , the ends of the handles of the ladles j , Then a pipe is made from copper; it has a lead ball inside it and bo

Basic Difference The turbine is one which convert the kinetic energy of the wind into the electrical energy while pump is a device which convert the rotational energy of it s impeller into the pressure energy of the fluid Work Out Put A pump out put is increased pressure energy or increase flow rate of liquid whereas in turbine out put is the electrical energy The Operating Principle fast moving fluid strikes the blades of turbine and cause them to move. Blades are attached to shaft which is attached to generator which produce electrical energy while in pumps electrical energy cause the impellers to move which exerts there force onto the surrounding fluid and force the fluid to move Types There are two main types of pump rotodynamic pump and positive displacement pump and  while turbine has hydro turbine, wind turbine and steam turbine

There are five types of gears namely: spur gear, helical gear, bevel gear, worm gear (worm and worm wheel), and rake and pinion gear.  Based on advantages and disadvantages of different types of gears, each type of gear is used for a different purpose and these gear types manly differentiate based on how they transfer power. Different Types of Gears Spur gear  Spur Gear is one which has teeth profile cut parallel to the axis of the gear as shown above. It is used for transfer of power in parallel shafts. Advantages and Disadvantages of Spur Gear Advantages of spur gear They offer constant velocity ratio Spur gears are highly reliable Spur gears are simplest, hence easiest to design and manufacture A spur gear is more efficient if you compare it with helical gear of same size Spur gear teeth are parallel to its axis. Hence, spur gear train does not produce axial thrust. So the gear shafts can be mounted easily using ball bearings. They can be used to transmit large amount of power (of t

Chain drive and belt drive mechanisms are two main mechanisms to transfer power and rotational motion.  Both belt drive and chain drive mechanism have their own advantages and disadvantages and particular applications. We have developed a comprehensive comparison between chain drive and belt drive.  This make it easy to know the difference between chain drive and belt drive mechanism in power transfer. Chain drive vs Belt Drive Difference between materials of belt and chain Looking at the material form which chain drive and belt drive mechanism are made.  A chain drive mechanism is made of metallic alloys like alloy steel while the belt drive mechanism is made up of polymers material.  Comparing working conditions for chain and belt drive Talking about the working conditions, chain drive can work in high temperature and in moist conditions whereas belt drive need dry condition for proper working. Efficiency comparison of belt drive and chain drive Because of the slippage efficienc
