A uniform beam is to be picked up by crane cables attached at A and B. Determine the distance afrom the ends of the beam to the points where the cables should be attached if the maximum absolute value of the bending moment in the beam is to be as small as possible. (Hint: Draw the bending-moment diagram in terms of a, L, and the weight per unit length w , and then equate the absolute values of the largest positive and negative bending moments obtained.)
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!
