Unformatted text preview: 4. A rigid bar is pinned at its left end and supported by two springs as shown. Find the equivalent spring constant that relates the force F to the vertical displacement at the right end of the bar. 5. Verify the expression in Table 1.2 for the equivalent spring constant for a uniform pinned-pinned beam with a force at midspan. Derive the beam deflection from the ordinary differential equation , where is the bending moment in the beam resulting from the concentrated midspan load. 6. Problem 1.29 in the textbook, but let the beam be pinned at both ends, rather than fixed. Are the beam and spring in parallel or in series? 7. Problem 1.30 in the textbook....
