Q.1
Which of the next statements cannot be used for the development of the force laws diagrams? (All the true statements can be used in the majority of the cases using acceptable simplifications)
*
The maximum value of the bending moment in a generic stretch can be calculated by introducing in its equation the value of “x” obtained by making equal to zero the equation of the shear forces in said part of the structure
The maximum value of the bending moment in a generic stretch can be calculated by introducing in its equation the value of “x” obtained by making equal to zero the equation of the shear forces in said part of the structure
The derivate of the bending moment with respect the longitudinal coordinate (usually named “x”) is equal to the shear force in the same point of the structure
The shear force is equal to its maximum value in the points where a hinge joint is found
