Obtain the deflection equation the simply supported beam has length l l, elasticity modulus e e, and cross-section with moment of inertia i i. a concentrated force is applied at half point, as illustrated below the deflection curve for the the first half of the beam is given by: y 1 ( x ) = p e i ( − l 2 x 16 + x 3 12 ) y1(x)=pei(−l2x16+x312) obtain the equation for the deflection curve y 2 ( x ) y2(x) for l / 2 < x < l l/2
