जब एक आबद्ध बीम (fixed beam) का एक सिरा δ से विचलित (deflect) होता है, तो विचलित सिरे पर बंकन आघूर्ण (bending moment) कितना 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)?

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:
