Assalam o Alaikum warakh matullahhi wabarakatu Sir if you will use shear modulus to find force answer will equal to book's answer

[@OnlineEducationist]

W. Salam Ok Thank You Jazalallah

[@cocwithm6495]

at last why using that formula while in second last we have used any other formula for strain energy

[@misbahmaryam9578]

Thanks alot ❤

[@NalainZehra-o7r]

Sir last one me apny jo formula use kiya ku kya he second last me tu dosra use kiya tha strain energy ka

[@ShumailaIrum-f5h]

Yes sir how the formula is changed?

[@Aishaimran-f3u]

I think probably the reason for this is that we don't have the values to use formulas which are used in previous numericals that is why we used another formula

[@muhammadshukat-3731]

I think ques may value Ys ki likhi 20... Jb kay hmy kha ha jo force provide kr ri shear strain Agr book kay page 114 pr dky to shear kay liay hmy jo value ha wo 8 .0 HA × 10 ^ 10 AGR SLOVE KRIN THEN 80 × 10 ^ 9 A JATA IS TRHA ANS SLOVE KR KAY SARA AT THE END 5.2 AY GA IN SHORT BOOK KAY NUMERICAL MAY VALUE WRONG HA YS: 20× 10 ^ 10 ❌ Shear .. : 80 × 10 ^ 9💯

[@MeharNaseer-st3uk]

book answers doesn't match

[@soniaarif4750]

1st problem main Y ki value 8×10^10 looo....bcz length main to change NAHI aa Raha yeh ....agr ap ke pas nbf ki book hai to pg 114 pr Jo table hai uss ko dekh lo

[@ayaanrizwan5688]

First numerical answer is 5.2kg in book sir please tell which one is right

[@PafKnights-x6h]

Book answer is wrong

[@maheen.fatimah]

it is right

[@ItsJerry-j5t]

On the keybook they use the formula Delta x = 1f/SA *L

[@Starfish.roblox]

Actually according to the given information in numerical the mass is 13 kg as the Ys in given data is 20×10*10 See table 7.1 the shear Ys value is 8×10*10 if we put this then the mass will be 5.2kg I would say that Ys value is given wrong in numerical it should be 8×10*10 as we r talking about shear strain

[@FatimaBilal-mk8ly]

Muja ak bat smj nhi ahi Numerical 3 ma jab ms ma ham na 10 likhi mass to phir mb ma kue nhu likhi

[@Alihassan-d6o5d]

🎉🎉🎉❤❤❤❤❤❤😊😊😊😊

[@ShumailaIrum-f5h]

Why the answer's are not according to the book???

[@MuhammadZayyan258]

Kuka mostly answer book per ghlat ha

[@Eman-cy5xx]

Ni Ni

[@Eman-cy5xx]

😅😅😅😅😅😅😅😅no

[@AbdulRehmanShah-tc9hz]

Ap ne mass bi nai mention Kia🤣🤣🤣

[@PakhtoonMathematics-vs8wc]

I am kind😂

[@nimrazuberi7630]

Acha
