सर आपका काम काफी हेल्पफुल है सेल्फ प्रेपरिंग स्टूडेंट के लिए शानदार बहुत शानदार लेकिन सर पर्टिकुलर सब्जेक्ट के विडियो को सीरियल वाइज अपलोड कीजियेगा प्लीज...................धन्यवाद
Thanks sir if you have time try to make it in hindi to reach a bigger audience,i also mistakenly found out this channel and comes out to be great channel
Sir in 29th question trapezoidal profile of force vs displacement is given sir so area under trapezium will be different sir, so can we use F(s)=[F(max)/pt*s1] ?
@@sunilmohodmh31 thanks so much Sir.This value of shear is provided to either punch or die to reduce the maximum force required for the sheet metal operation. right sir?
bcoz cutting area is perimeter, if we are cutting a rod in that case we take cutting area as pi/4 x D^2 but when you are punching a hole on flat sheet the cutting area will be pi XD
Dear sir, what we do if we dont get or dont know the penetrations . Can you please let me know how much force is required to cut the blank on a s.s 304 grade sheet & also give me the calculation Size is ( rectangle in shape ) length 74 m.m Width is 24 m.m Thikness 4 m.m Thank you Waiting for your valuable reply sir
sunil mohod sir first of all thank you for your reply. I dont get you sir i dnot know the penetrations value of s.s. so how can I get or assumed the value.
Thank you so much sir.
Very brief and crisp explanation.
Really helped me and expecting more lectures from you. Once again thank you so much
thanks please share in your group
Loved it .. amazing .. thanks a lot for this .. best work ever seen in youtube videos .. !
Hatsoff !!
Such a nice video thanks for the knowledge 😊
The process is Excellently explained sir
Excellent is an understatement for this video

To the point information and lots of numericals to practice. Thanks a lot sir

What is standard value of shear stress for galvanized iron sheet?
Do you have an example but using RPET?
sir your are the best
SIR, if more than one hole is to be punched of one dia and another hole of differnt dia in a sheet of given thickness what would be the punching force
Forces for each hole is to be added for the compound operation.
And the maximum of the two forces is taken for the staggered operation.
Wonderful lectures for GATE sir
Can someone suggest a good textbook to find this content as well? Thank you!
refer production engineering by PC SHARMA

Sir
Please help to give an example for getting cutting force required for round steel bar by power press. How much capacity power press required ton.
Nice vedio sir
How to find angular clearance of punching and blanking die ? Plz explain with example .
very very good explanation sir.
Ultimate video sir
Sir In Q 26 in fmax why u divide with 9.81??
Newton to kg
9.81 is value of earth gravity - so, 1 kg x 9.81 = 9.81 N
Sir what does "s" denotes?
Length of shear

@@navinpn410 yes
Sir,
you please make video on different types of engineering materials along with different standards.
thx.
Sir how to use formula of shear force to cut sugarcane??
cutting area of suger cane ( pi/4 x D^2 ) x T x shugar cane shear strenth
Area ke liye to lband thickness multiply karte h
Sir perimeter hum Kyu nikalte h
LBH multiply Kyu nhi karte plz reply sir
bcoz cutting area is perimeter, if we are cutting a rod in that case we take cutting area as pi/4 x D^2 but when you are punching a hole on flat sheet the cutting area will be pi XD
Sir where is shear cutting part 1
Will upload in week
It is on dimensions cal for die and punh
Sir is example 28 answer is write??? It seems like you took p*t value wrong?? Or any explanation for it?
p/t=0.2 therefore for thickness t= 5mm the punch travel is 0.2 x 5=1mm
No correction
Dear sir, what we do if we dont get or dont know the penetrations .
Can you please let me know how much force is required to cut the blank on a s.s 304 grade sheet & also give me the calculation
Size is ( rectangle in shape )
length 74 m.m
Width is 24 m.m
Thikness 4 m.m
Thank you
Waiting for your valuable reply sir
Take penetration =1/3 for steel
sunil mohod sir first of all thank you for your reply. I dont get you sir i dnot know the penetrations value of s.s. so how can I get or assumed the value.
thickness /3
sunil mohod sir du you mean total thikness divided by 3???
If its then the ans will be like this 4 ( thikness ) ÷ 3 = 1.33... is that??
stock thickness/3
very good sir
sir p/t=0.2 is also create problem for me.give some explanation please
distance traveled by punch to thickness ratio is 0.2 for 5 mm thickness , the punch will travel 5 x 2=1mm
Sir there will be p/t =0.2 p*t=0.2*5*5=5mm
Sir if you explain a little more and slowly it would be more helpful
Superb
Thanks sir
Watch at .5x speed
Thanks me later
Apko Gate academy se ku6 sikhna chahiye kese padhate hai.bullshit!!
