r unit over thewhole span, fixed at both ends. Origin at left support. Fig. 51. As in the previous case, the reaction at either end may berepresented by ^wl + Q. The shear at x is ^wl—wx, which ex-pression changes sign at the middle and at either point of support;hence at those places will be found… … Fig. 51 the negative moment at each point of support. If x = \lf M at middle = 7£;/2(i-i-^^) = —. 24 Substitute the vakie of Qb and get Ma^=-^w(x^-lx+lP), dv w dx lEI (1^3_l/,v2 + l/2^). w /x4 Ix^ Px^ \ 2EI\i2 6 12 / RESTRAINED AND CONTINUOUS BEAMS. Ill Since v = o when x=o, C =o. When x = U,…
