Solve each of the following problems. Show your solution. 1. A hydraulic lift office chair has its seat attached to a piston with an area of 11.2 cm2. The chair is raised by exerting force on another piston‚ with an area of 4.12 cm2. If a person sitting on the chair exerts a downward force of 219 N‚ what force needs to be exerted on the small piston to lift the seat? Answer: a= 11.2 cm2 A= 4.12 cm2 f= 219 N F= 80.56 N F= fA / a ;

G- Isiah Thomas: 1981-1994 When you think of the “Bad Boy” Pistons of the 80s and 90s‚ you think of Isiah Thomas. Despite his small stature‚ Thomas embodied everything that encompassed those Pistons’ teams. He was a general on the floor- his tough on-court demeanor and physical play style made him the perfect leader for the “Bad Boys”. Thomas spent his entire 13-year career with the Pistons making the playoffs in nine of those seasons‚ and ultimately winning two NBA championships. He’s the franchise’s

released‚ drives the piston forward (Fig. 1). The piston strikes on the shank adaptor. The kinetic energy of the piston is converted into a stress wave which travels along the drill string to the rock. In order to obtain the best possible drilling economy the whole system‚ i.e. rock drill‚ drill steel and the rock‚ must harmonize. Part One - Wave shape and output power Theoretically‚ the wave has a rectangular shape. Its length is twice that of the piston‚ while its height (Fig

Matt Bagley English 110 Process Essay Process of a 4-stroke Internal Combustion Engine A common phrase that is heard whilst growing up is "curiosity killed the cat". This phrase might be true but; "ingenuity brought the cat back". Having a mindset in which giving up is never an option has plagued most inventors of the modern day‚ especially a high school drop out named Nikolaus August Otto‚ born in 1832. Otto was responsible for the development and improvement of the 4-stroke motor that

manufacturing of Sportsman Race Series aluminum slipper pistons (Probe Industries) that are used in the Chevrolet LS Series V8 engines. The designs of two sets of jig and fixture designs are proposed. The first set (two vee-blocks and a drill bushing) is designed for the process of drilling the wrist pin holes in the piston. The second design (two vee-blocks and a pin locator) is used in the milling of the skirts and lower form of the piston. The designs use principles of manufacturing facilities

since the 1890s: In the first approach‚ the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air as the working fluid for the additional power stroke.[1] The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. There are two power strokes: one with fuel‚ the other with steam or air. The currently notable designs

WANKEL ENGINE The Wankel engine‚ invented by German engineer Felix Wankel‚ is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. Its four-stroke cycle takes place in a space between the inside of an oval-like epitrochoid-shaped housing and a rotor that is similar in shape to a Reuleaux triangle but with sides that are somewhat flatter. This design delivers smooth high-rpm power from a compact size. Since
