दोनों सिरों पर आबद्ध (fixed) एक एकल-बे, एकल-मंजिला पोर्टल फ्रेम के लिए, यदि अक्षीय विरूपण (axial deformation) को उपेक्षित कर दिया जाए, तो शुद्धगतिक अनिश्चितता की कोटि (degree of kinematic indeterminacy) 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:
