Computer Project 1
Project Description
Consider an arbitrary 2D truss structures. An example is shown in Figure 1.
Figure 1
This is a truss with three members [1], [2] and [3]. These members are connected, by pins, at
nodes 1, 2 and 3. The coordinates of the nodes are: (0,0), (1,0) and (0.5, 0.5*sqrt(3)) in the unit
of ft. The boundary condition at nodes consists of a mixture of loads applied and displacements
prescribed. For example at node 1, both the horizontal and vertical components of the
displacement are prescribed to be u1=0 ft and v1=0 ft. At node 2, the vertical component of the
displacement is prescribed to be zero (v2=0 ft) while the horizontal component of the load is zero
(P2=0 lb). Finally at node 3, both horizontal and vertical components of the load are given
(P3=1000 lb, Q3=1000 lb). The further details of the truss structure are covered in Statics.
Your task is, given an arbitrary 2D truss structure with the prescribed load and displacement
boundary conditions, to plot the geometry of the truss structure along with the boundary
condition.
As a matter of fact, Figure 1 was plotted by MATLAB. The features required in the
plot are as follows:
