Hindi na po ba kasama tickness ng mga hole

[@QueneeChinKao]

Hello ask ko lang po sana if required po ba na kunin Wn every path? Or kung saan po mas maraming staggered holes don po lagi yung mag gogovern na An?

[@cebox]

Usually and actually, mas makakakuha tayo ng mas mababang Area net sa mas maraming holes. Kaya mas maganda dun sa maraming holes ang unahin. Then, mas convenient gamitin ang wn kesa sa kinukuha mo agad ang Area, kasi once na makuha mo ang wn, then multiply mo lang ng thickness. As simple as that./ (𝗦𝗼𝗿𝗿𝘆 𝗳𝗼𝗿 𝘁𝗵𝗲 𝗹𝗮𝘁𝗲 𝗿𝗲𝗽𝗹𝘆.

Hello po. Pa clarify lng sa Ag. Basta angle, ang pagkuha sa Ag= (L-t)(t) + (W)(t)? Ang alam ko lng kasi na Ag is for plate na Ag= tW. Thank you.

[@JmDags-s5i]

Yes po kasi kinukuha po niya yung buong area which is hinati nya po sa dalawa yung naka letter L na angle. Which is yung Area 1 nya is yung naka horizontal na area 150x13 which is yung (W)(t) mo. At yung Area 2 niya is yung naka vertical which is yung nakadikit sa gusset plate 200-13(13) which is yung (L-t)(t).

[@JmDags-s5i]

At yung Ag=tW naman po. Kaya po naging tW lang po yan is plane lang po kasi sya. Bali yung area nya po is isa lang na naka rectangular. At sa pagkuha lang nmn ng area po kapag naka rectangle is Base x Height. Which is yung height nya is yung t at yung base namn nya is yung W po.

[@chrischan5134]

Di po ba dapat 4 ang holes sa flange?

[@cebox]

Paano pong 4, engr?

[@johnangelo3992]

I mean lima po

[@andressharlonej.4640]

​Na fix rin ata sa video

[@raychesterlapura411]

Bakit po sa iba is 22 mm + 2 mm lang yung dinadagdag for the hole diamter? Sana masagot po.

[@cebox]

In NSCP 2015 po, 2mm for diameter hole, pero kapag given is diameter bolt, times 2 ang 2mm, kaya 4mm. Now, sa board exam, ang ginagawa karaniwan is nilalagay na lang kung ilan ang iaadd para sa hole, minsan 2mm or 3mm. (Sorry for the late reply, huhu. Nabusy sa live tutorial, work stuff, and masteral. BUt we do hope na makasagot pa rin questions/concerns po ninyo. God bless po!)

[@niadelossantos1199]

Ano po Sir pinagkaiba if gamitin ang Wn sa An?

[@cebox]

Nothing. Same lang naman po ang magiging sagot, ang Wn need lang ng thickness para maging An, ang An, mismong net area na po.

[@fritzgunthertuliao3203]

Bakit ho hindi nio ni multiply yung (number of holes at diameter) sa thickness ng plate?

[@cebox]

Width palang sinosolve, hindi pa area. (𝗦𝗼𝗿𝗿𝘆 𝗳𝗼𝗿 𝘁𝗵𝗲 𝘃𝗲𝗿𝘆 𝗹𝗮𝘁𝗲 𝗿𝗲𝗽𝗹𝘆. 𝗪𝗲'𝗿𝗲 𝗷𝘂𝘀𝘁 𝗯𝘂𝘀𝘆 𝘁𝗵𝗲𝘀𝗲 𝗽𝗮𝘀𝘁 𝗳𝗲𝘄 𝗺𝗼𝗻𝘁𝗵𝘀 𝗶𝗻 𝗼𝘂𝗿 𝗽𝘂𝗯𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝘀𝗮 𝗠𝗮𝘀𝘁𝗲𝗿𝗮𝗹, 𝘀𝗮 𝗧𝗵𝗲𝘀𝗶𝘀, 𝘄𝗼𝗿𝗸 𝘀𝘁𝘂𝗳𝗳, 𝗮𝗻𝗱 𝗹𝗶𝗳𝗲. 𝗛𝗼𝗽𝗲 𝗻𝗮 𝗻𝗮𝗸𝗮𝘁𝘂𝗹𝗼𝗻𝗴 𝗮𝗻𝗴 𝗖𝗘 𝗕𝗼𝘅 𝘀𝗮 𝗶𝗻𝘆𝗼𝗻𝗴 𝗽𝗮𝗴𝗮𝗮𝗿𝗮𝗹. 𝗧𝗵𝗮𝗻𝗸 𝘆𝗼𝘂 𝗮𝗻𝗱 𝗚𝗼𝗱 𝗯𝗹𝗲𝘀𝘀!)

​@@ceboxsir pano po pag magkaiba ang thickness? San imumultippy ang Wn?

[@jesicamarisikat724]

Hello, sana po masagot, sa reference niyo po na Segui sa example 3.7 page 76 sa pdf, bakit po nagsubtract ng s^2/4g? Pero sa formula and dito po sa example niyo, addition siya? Nalilito po ako kagabi pa huhu salamat po

[@cebox]

Check niyo po yung solution, kung minus ginawa ni Segui, sigurado ang kinukuha palang niya ay yung d'. Kapag plus, meaning, sinama na niya si d' sa Wn. Take note, d' = ∑d - ∑s^2/4g Wn = Wg - (∑d - ∑s^2/4g) Negative x Negative = positive (𝗦𝗼𝗿𝗿𝘆 𝗳𝗼𝗿 𝘁𝗵𝗲 𝘃𝗲𝗿𝘆 𝗹𝗮𝘁𝗲 𝗿𝗲𝗽𝗹𝘆.

sir bakit nga same ang An at Ae dito sa fracture failure?

[@cebox]

Dahil lahat ng element ng angle bar is nakaconnect po. (Sorry for the very late reply. Sobrang abala lang po sa masteral thesis and work stuff. But hopefully, makatulong/nakatulong pa rin ang aming sagot sa inyo. God bless po!)

dipuba yung layer na nasa 60 is 35? dapat

[@cebox]

Saang part po tinatanong po ninyo? (Sorry for the very, very late reply as CE Box is very busy with his Master's Degree, Accreditation, Work Stuff, and Life. Thank you for understanding. Keep in touch with CE Box as we plan to do more video tutorials.)

[@megankayetagalog5791]

55+60-150= 35, bakit 60 na lagay?@@cebox

[@carmieguimbatan7776]

yung distance ng 1st layer ng bolts to second layer of bolts po ba tinutukoy nyo? tama po na 60 sya. dahil ang g"gage" spacing ay center to center distance ng bolts, and based sa side view, 60 po sya.

[@carmieguimbatan7776]

center to center spacing po ng magkatabing holes, baka po nalito kayo sa ginawa nung nakuha yung 117. mas maiintindihan if iimaginine mo na pinatayo mo or straighten yung angle bar, so mas makikita yung gage spacing ng each hole, kaya 117 yung nasolve na distance ng second layer to 3rd layer .@@megankayetagalog5791

[@drinsgallery1309]

Hi clarification lang po bakit po pala naging 26 yung thickness?

[@nieuviesusvilla9229]

13 lang po yung thickness ng plate

[@nieuviesusvilla9229]

baka you mean po is the effective diameter which is 26 mm. if you are given bolt diameter db to make it effective de = db + 4mm. As per table 510.3.3 on Nominal diameter hole from NSCP 2015. If: db < 22mm ; dn = db+2mm ; de = db + 4mm if : db > 22mm ; dn = db + 3mm ; de = db + 5mm
