b) A parabolic two hinged arch has a span of 60m and a rise of 12m. A concentrated load 8kN acts at 15m from the left support. The second moment of area varies as the secant of the inclination of the arch axis. Calculate the horizontal thrust and reactions at the hinge. Also calculate maximum bending moment at the section
Thank you sir. You should have drawn BMD
Sir with due regards please be slow while explaining & also while speaking. It will be beneficial for slow learners.
Thank you sir 😊

Sir i am confuse in some topics of theory of structure .can we talk on whatsapp or any other online platforms where u available .
you can contact me through stankacademy@gmail.com
Same question was asked in SA EXAM
Thanks❤
