जब L लंबाई और EI नमन दृढ़ता वाले एक बीम सदस्य का सुदूर सिरा (far end) दृढ़ता से फिक्स हो, तो मानक प्रतीकों के तहत निकट सिरे (near end) पर सदस्य की घूर्णन कठोरता (rotational stiffness) क्या होगी?

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:
