Mechanical engineers help thread!!!

[KnightofHeaven007]

Ang layunin ng Mechanical Engineers help thread na ito ay para i bahagi sa bawat isa ung mga latest technology. Alam naman po natin na napag iiwanan ang mga engineer natin dito sa Pilipinas. Tatanungin kita bilang isang Mechanical Engineer ay may nakukuha kabang pakinabang sa PSME Organization?

Inaasahan ko po na sana lahat ng Mechanical Engineers natin dito sa Symbianize especially ung mga nasa abroad ay I share nila ung kanilang mga knowledge.

Eto po ang mga topic na nakapaloob sa atin thread

Auto cad
Power plants
Hvac / Hvacr
Manufacturing
Machine design

Pwedi rin po i post ung mga guides in maintenance , installation and troubleshooting of an unit.

Magtulungan tayo mga ka Engineer para umunlad ang ating bansa. Maraming salamat po!!

Note:
Ginawa ang thread na ito hindi upang ireplace ang mechanical engineering thread ni sir Jabaps kundi para lamang ito sa mga mechanical engineer na nagpapractice ng kanilang profession.

Paalala:
Iwasan po natin ung mga trash talk para maging kapakipakinabang ang ating thread. Respect others opinion

sino po ba nakaimbento ng scotch yoke mechanism at saka ano po pagkakaiba ng scotch yoke sa slider crank please pasagot po ,, need lang po

Scotch yoke ​

The Scotch yoke is a mechanical device that converts the horizontal motion of a back-and-forth sliding bar into a rotational motion, or converts rotational motion to horizontal motion, also called linear motion. The parts of a Scotch yoke include a sliding bar, a yoke on that bar with a slot cut out, and a smaller bar connected to the yoke and affixed by a pin through the yoke slot to the sliding bar. As the bar slides back and forth, or reciprocates, the smaller bar is forced to slide up and down in the yoke slot, creating a rotational movement.

In many internal combustion engines, linear motion is converted into rotational motion by means of a crankshaft, a piston and a rod that connects them. The Scotch yoke is considered to be a more efficient means of producing the rotational motion as it spends more time at the high point of its rotation than a piston and it has fewer parts. As a disadvantage, the Scotch yoke suffers more wear and tear and has a shorter useful life, which reduces its effectiveness for constant use.

The Scotch yoke was used as an energy conversion device for the Bourke engine, a two-stroke engine developed early in the 20th century by engineer and inventor Russell Bourke. With far fewer moving parts because of the Scotch yoke, it was considered more efficient than other engines, produced greater power for its weight and produced lower emissions. Critics challenged its benefits saying the engine would run too hot and lose efficiency and need extra casing to compensate for the double motion required by the Scotch yoke, which would offset the weight to power advantage. Bourke developed working prototypes prior to World War II, but the engine was never widely produced. The Scotch yoke continues to be used in some engines, particularly engines driven by steam or hot air.

Non-combustion uses of the Scotch yoke focus on its benefits in construction of actuators for high pressure pipelines. An actuator is used to convert the flow of liquid or steam into energy or to slow or stop the movement of the substance in the pipeline. A Scotch yoke actuator converts the linear motion of the substance through a pipeline to a rotational motion which can be used to produce energy. Similarly, by adjusting the transfer from linear movement to rotational, the Scotch yoke actuator can stop or regulate the flow of a substance through a pipeline.

Share naman kayo guys ng Autocad tutorial for beginner.. mahina kasi ako eh, lang hiya kasi prof. namin minsan lang magpakita..hehe
engineer pa lang ako last september..

baka may topic kayo dyan sa research Method.. penge naman

 

[FUuuuuu]

PSME? di ko na kinuha card ko kakatamad XD

Research? tara mag research. anu klaseng research? may prototype?

pa help po nito please salamat po

Q2BBCQ4EFPS is a compound linkage. Q2 and Q4 are fixed centers on a horizontal line with Q4 7.5 inches to the right of Q2. Q2B, 3.5 inches long, oscillates above Q2. CQ4 is a crank 2 inches long that rotates about Q4. BC is a connecting rod 7 inches long. P is an oscillating bearing block that is pivoted at a fixed point 4.5 inches above Q4. EF, 8.5 inches long, which is pinned to the mid point of the connecting rod BC at E, extends through the oscillating block at P. F is connected to a slide 7 by a link FS, 6.5 inches long. The slide 8 moves in a vertical guide whose center line is 1.5 inches to the right of Q4. Q4C rotates uniformly counterclockwise at 30 rpm and has turned through an angle of 150 degrees from right horizontal position, causing S to be below Q2Q4.

The problem was retrieved from Elements of Mechanism by Doughtie and James, p.471 - L-8.

mga ka ME san kaya makakabili ng book na MACHINE DESIGN by JAS TORDILLO? salamat

 

[reyncruz09]

Cno po ba may mechanical engineering board reviewer by Galvizo Subaran?

 

[rajiv123]

sino my notes sa mepfs design?salamat

 

[SEw910i]

Good day Engineers!
Baka po may alam kayong electric motor vibration standard na libro?
Pa share naman mga sir

Fresh grad ako at boardpasser last Feb 2019. Nagpahinga muna ako tapos ngayon gusto ko muna iimprove yung technical skills ko aka. yung hands on skills. Gusto ko sana sa HVAC field, saan kaya maganda kumuha ng experience o pwede magtraining?

Cno po ba may mechanical engineering board reviewer by Galvizo Subaran?

parang wala pa akong na encounter na ganyang author sa ME reviewers. Anyway, anong subject specifically yan?

 

[Shaqattack]

Pahingi po ng pdf book, sa MEPF, HVAC and Mechanical Design para sa standards and procedure. Salamat
