To draw the Shear Diagram

V_A = -1000 lb
V_B = V_A + Area in load diagram
V_B = -1000 + 0 = -1000 lb
V_B2 = V_B + 500 = -1000 + 500
V_B2 = -500 lb
V_C = V_B2 + Area in load diagram
V_C = -500 + 0 = -500 lb
V_D = V_C + Area in load diagram
V_D = -500 - 400(4) = -2100 lb

To draw the Moment Diagram

M_A = 0
M_B = M_A + Area in shear diagram
M_B = 0 - 1000(2) = -2000 lb·ft
M_C = M_B + Area in shear diagram
M_C = -2000 - 500(2) = -3000 lb·ft
M_D = M_C + Area in shear diagram
M_D = -3000 - ½ (500 + 2100)(4)
M_D = -8200 lb·ft
