Chapter 16.2, Problem 16.151P
(a) Determine the magnitude and the location of the maximum bending moment in the rod of Prob. 16.78. (b) Show that the answer to part a is independent of the weight of the rod.
16.78 A uniform slender rod of length L = 36 in. and weight W = 4 lb hangs freely from a hinge at A. If a force P of magnitude 1.5 lb is applied at B horizontally to the left (h = L), determine (a) the angular acceleration of the rod, (b) the components of the reaction at A.

Two live loads of 7 KN and 9 KN separated 5 m apart,
are to cross a simple beam. Also, a uniform live load of 6 KN/m,
6 m long, is expected to cross the same beam. The simple
supports are marked A and B and a point C is located 4 m from
A. Determine: (a) the maximum moment at C due to the two
concentrated live loads if the length of the beam is (a.1) 8.4 m;
(a.2) 10 m.
(b) The maximum moment at C due to the uniform live load if
the length of the beam is (b.1) 8.4 m; (b.2) 10 m.
(c) The maximum moment in the beam due to the combined
effects of the two concentrated live loads and the uniform live
loads if the length of the beam is (c.1) 8.4 m; (c.2) 10 m.
part (c), I am asking for the
ABSOLUTE maximum moment in the beam due to the
combined effects of the two live loads and the uniform
live load. Please be guided and informed accordingly.
Good luck!
