कॉलम सादृश्य विधि (column analogy method) में, L लंबाई और EI नमन दृढ़ता (flexural rigidity) वाले एक आबद्ध बीम (fixed beam) के लिए सादृश्य कॉलम (analogous column) का क्षेत्रफल क्या लिया जाता 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)?

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:
