Item 1
For the beam given below, the boundary conditions that would be used to solve for the constants of integration
resulting when the Method of Integration is used to determine the equation of the elastic deflection curve are:
ANSWER:
At , and are maximum values
At ,
At ,
At , and
x = 0 v v′
x = 0 = 0v′
x = 0 v = 0
x = 3 m v = 0 = 0v′
Item 2
For a beam like the one given in the video problem, 2 moment equations, written as functions of x, define the
internal moment along the beam’s length. When the method of integration is used to determine the equation(s)
of the elastic deflection curve, _________________ boundary and or continuity conditions are required to solve
for the constants of integration that result.
