Essentials in the theory of framed structures . 3. The beam in Fig. 59 supports a uniform load of 200 lb. Sec. Ill APPLICATION OF PRINCIPLES OF EQUILIBRIUM 91 per foot. The shear diagram starts with a positive ordinate =1,600 lb. at S, decreasing uniformly 200 lb. in each foot from Sto C. Beyond C the ordinates are negative, and increasing200 lb. per foot to —1,600 lb. at T. Since the ordinates in theshear diagram are uniformly varying, the slope of the momentdiagram will be uniformly varying; and the bending momentdiagram will be represented by a curved line instead of a seriesof broken lines
