question : how to plot bending moment diagram in python from numpy import * import matplotlib.pyplot as plt print('all dimensions are in meter (m)/n all loads in kn'); l= 6; c = 4; d = 10 f= 8; ra = 11; rb = 11; x1 = arange(0,1,.01) x2 = arange(1,3,.01) x3 = arange(3,4,.01) x4 =arange(4,6,.01) p1 = ra*x1; p2 = ra*x2-4*(x2-1); p3 = ra*x3-4*(x3-1)-10*(x3-3); p4 = ra*x4-4*(x4-1)-10*(x4-3)-8*(x4-4); plt.plot(x1,p1,x2,p2,x3,p3,x4,p4) plt.show()
