Unformatted text preview: PROBLEM 10.61
Using the method of Section 10.8, solve Problem 10.31. SOLUTION Spring: Unstretched length: AE = x = 2 ( 2l sin ) = 4l sin x0 = 4l sin 30 = 2l s = x  x0 s = 2l ( 2sin  1)
V = = 1 2 ks + PyC 2
2 1 k 2l ( 2sin  1) + P ( l cos ) 2
2 Deflection of spring V = 2kl 2 ( 2sin  1) + Pl cos dV = 4kl 2 ( 2sin  1) 2cos  Pl sin = 0 d (1  2sin ) cos P + =0 sin 8kl 2sin  1 P = 8kl tan ...
