SFD and BMD of a continuous beam

• Calculate reactions at supports

• Draw SFD by taking sections and finding net forces

• Draw BMD by integrating SFD

• Identify points of maximum bending moment

• Check for shear and moment continuity at supports

The moment of inertia of an I section can be calculated using the formula and dimensions of the section.

• The moment of inertia is a measure of an object's resistance to changes in rotation.

• The formula for moment of inertia of an I section is (bd^3)/12 + 2[(b/2)^2t^3]/3, where b is the width, d is the depth, and t is the thickness of the flange.

• The moment of inertia can be used to calculate the bending stress and deflect...read more

Zero member force in a truss refers to the absence of any tension or compression force in a particular member of the truss.

• A zero member force can occur in a truss when the external loads are balanced and the truss is in a state of static equilibrium.

• The method of joints and method of sections can be used to determine the zero member forces in a truss.

• Zero member forces can also occur in symmetrical trusses or when cer...read more
