    Hi. Thank you for your videos. When you intridoce shear force in minute 13.00, some books assume that the sum of moments must multiply the shear force by deltax/2. Could you kindly let me know why is shear force multiplied by deltax/2?

    Hello 👋🏻 Sir, Loads of Love from India. You are a great teacher sir, I studied my Engineering and many Concepts were not clear even after working for many years, but in just 2 classes of yours those concepts are clear. Hope you are doing good, you promised the videos will come regularly but, 🙁 stopped again . Hope everything is fine with ? Please reply and upload the remaining Dynamic classes sir . You are a great teacher and a beautiful Human Sir, Many many Thanks !!

    How much factor of safety to be considered for A36 steel to find allowable stress ..I considered 4 Safety of factor and max allowable stress as 62MPa.

    • @prometheusengineeringgroup7825

      This is something that the particular jurisdiction code will prescribe depending on bending, shear, compression etc.

    I'm really late to the party, but I wanna ask. As far as I can see, the sigma1 formula only stays true for elastic stage of the material, so would the shear stresses formula. What'll happen if the cross-section approach the plastic stage? Will the formula change? If it does, then what is the universal way to calculate?

    • @prometheusengineeringgroup7825
      @prometheusengineeringgroup7825 3 ปีที่แล้ว

      Correct. The video on the plastic section m modulus will give you the clue as to the manner in which the formula changes

    Ike I am a young structural engineer and I have found your videos incredibly useful.Very concise and to the point. In particular the two videos about structural dynamics has helped me improve my understanding on these advanced topics as this is something I had previously struggled to understand. I can't thank you enough for putting these videos out.
