Question

The horizontal beam is supported by springs at its ends. lf the stiffness of the spring at A is kA = 5.0 kN/m, determine the required stiffness of the spring at B so that if the beam is loaded with the 800-N force it remains in the horizontal position. The springs are originally constructed so that the beam is in the horizontal position when it is unloaded. (Figure 1) Figure 1 of 1 Determine the stiffness of the spring at B. Express your answer to three significant figures and include the appropriate units. kB = Submit My Answers Give Up

Explanation / Answer

kax*1=2kb*x both x are same as bar is horizontal then 2.5N/m=kb
