Unformatted text preview: + (0.5 + t u 2 ) 2 − L 2 (4) 0.5 + t u From the geometry, tan t = 2 , t u t 2 = −Δ , R = − P (5) 5 − u 2 1 Eq. (1) and (2) are the force equilibrium equations. We use them by assuming a Δ , t t solving from equation (1) for u 1 , then substituting u 1 and Δ into the equation (2) to obtain the corresponding P. We can also solve them in different way. We first assume t t ө and then calculate u 1 and Δ . P ×10 4 Vs. Δ EA 3± P ×10 4 Vs. Δ Using ADINA EA Displacement u 1 Vs.
