b)
With the vertical spring, determine the overall stiffness of the system with both the force
and displacement are vertically downward at B.
Transcribed Image Text:b) With the vertical spring, determine the overall stiffness of the system with both the force and displacement are vertically downward at B.
Figure 1 shows a simply supported beam with a concentrated force P applied at the mid-span,
B. Given the modulus of elasticity is E = 210GPa. To reduce the displacement of the system, a
vertical spring with spring constant ks is installed at B as shown in the figure.
