6 मीटर लंबाई की एक आबद्ध धरन (fixed beam) पर 30 kN/m का सम-वितरित भार (UDL) लगा हुआ है। इसके आबद्ध सिरों पर उत्पन्न होने वाले आघूर्ण (fixed end moments) क्या होंगे?

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)?

Method of joints is applicable to calculate member forces of a truss, when the number of unknown forces at the joint under consideration is not more than:
