CYLINDER VERTICAL OSCILATING STEAM ENGINE

CYLINDER VERTICAL OSCILATING STEAM ENGINE Operation The  steam  needs to be fed into the end of the cylinder at just the right time in the cycle to push the  piston  in the correct direction. In the other direction, the steam needs to be allowed to escape from the cylinder. As the  crankshaft  rotates, the  piston rod  moves up and down (or side to side in the case of a vertical cylinder) as well as in and out. Because the piston rod is rigid and the piston itself is long relative to its diameter, this causes the cylinder to rock, or "oscillate" on its special mounting ( trunnion ). In the design usually found in a toy or model engine, a hole in the side of the cylinder (one at each end for a  double-acting cylinder ) and a pair of holes in the port block are arranged so that this rocking motion lines up the holes at the correct times, allowing steam to enter the cylinder in one direction and to escape into the atmosphere or  condenser  in the other direction.

Mechanical engineering Mechanical engineering  is an  engineering  discipline that combines  engineering physics  and  mathematics  principles with  materials science  to  design , analyze, manufacture, and maintain  mechanical systems . It is one of the oldest and broadest of the  engineering disciplines . The mechanical engineering field requires an understanding of core areas including  mechanics ,  dynamics ,  thermodynamics ,  materials science ,  structural analysis , and  electricity . In addition to these core principles, mechanical engineers use tools such as  computer-aided design  (CAD),  computer-aided manufacturing  (CAM), and  product lifecycle  management to design and analyze  manufacturing plants ,  industrial equipment  and  machinery ,  heating and cooling systems ,  transport  systems,  aircraft ,  watercraft ,  robotics ,  medical devices ,  weapons , and others. It is the branch of engineering that involves the design, production, and operation of  machin
