Su 95 EGN 3420 EXAM 1 Name ___________________ SHOW ALL WORK! Problem 2 (35 pts) A cantilevered beam extending from its clamped end (x=0) to its free end (x=L) has a maximum deflection δ max at the end of the beam, i.e. at x=L. The deflection δ at location x= α L (0< α <1) is related to δ max by the equation f( ) / max α α α α δ δ = - + - = 4 3 2 4 6 3 0 Use the Bisection Method to solve for the value of α at which δ / δ max is equal to 0.75.
