Determine the bending moment acting at each of the following locations:

(a) x = 13.5- ft (i.e., just to the left of point B)
(b) x = 13.5+ ft(i.e., just to the right of point B)
(c) x = 17.0 ft (i.e. at point C)
(d) x = 23.0 ft

Note that x = 0 at support A. When entering your answers, use the shear-force sign convention detailed in Section 7.2.
Answers:

(a)	M =	kips-ft
(b)	M =	kips-ft
(c)	M =	kips-ft
(d)	M =	kips-ft

Use your shear-force and bending-moment diagrams to determine the maximum positive bending moment, M_{max, pos}, the maximum negative bending moment, M_{max, neg}, and their respective locations, x_{max, pos} and x_{max, neg}. When entering your answers for the maximum bending moments, use the shear-force and bending-moment sign conventions detailed in Section 7.2. The maximum negative bending moment is the negative moment with the largest absolute value. Enter the maximum negative bending moment as a negative value.

Answers:

M_{max, pos} =	kips-ft	x_{max, pos} =	ft
M_{max, neg} =	kips-ft	x_{max, neg} =	ft
