(Attempt TWO Questions Only)Q1:The truss shown is subjected to
external loading. Determine the displacement components of the free
node, the reaction force components. The elements have modulus of
elasticity and cross-sectional areas .4345O30O1 m
Q2:For the beam shown, determine the displacements and slopes at
the nodes, forces in each element, and reactions at the supports. E
= 1.4 x 106 psi, I = 2.4 in4100 lb
k=200 /in.
Q3: Consider the four-spring system shown. The spring constant k
= 200 kN/m and the displacement = 20 mm. Determine the displacement
and forces of each node and the element displacements and forces
for the specified conditions.
