The 1-meter base of this cantilever beam section is a symmetric fixed support. The left extension of the section is 12 m long and the right extension is 5 m

long. If the couple (reactive moment) at the fixed support is 160 Nm CW, what is the load density at the left side of the section? If the load density of at the left side of the section were reduced to 0 and the original 160 Nm couple was removed, what couple must be added at the fixed support in order to maintain equilibrium? What is the force reaction at the fixed support? (with the load density at the left side of the section at 0)
