एक थ्री-हिंज्ड आर्च (three-hinged arch) अपने पूरे क्षैतिज स्पैन पर समान रूप से वितरित भार (UDL) वहन करता है। यदि इसकी आकृति कैसी हो, तो आर्च पूरे खंड में नमन आघूर्ण से मुक्त होता है?

What is the value of maximum shear force for a simply supported beam of length 6.0 m, subjected to a uniformly distributed load (w kN/m) throughout the span, for which the bending moment equation at a section from the left support situated at 'x' m is Mx = 30x - 0.5(wx2)?
