Equilibrium and Support Reactions

Civil engineers deal with structures that are composed of several members connected or with individual members such as beams and columns. To analyze such structures, the condition of statics must be applied. Under the static condition, the members are considered to be in equilibrium under the action of forces, that is, the members are assumed to be having negligible velocity.

SOLVE FOR A AND B

The simply supported beam is built up from three identical
boards nailed together. The nails are spaced at 30 mm.
Let V = 300 N, b= 10 mm, and h = 180 mm. The
centroid is located = 122.8 mm from the right as shown in
the figure. The origin of the coordinate system is at the
centroid (green dot in the figure). The second area moment
of inertia about the y axis is Īy = 1.02x108 mm², and the
second moment of inertia about the x axis is I = 3.49x107
