7Ã¢â‚¬â€œ49. Draw the shear and moment diagrams of the beam

(a) in terms of the parameters shown; (b) set Mo=500 N Ã‚Â· m,

L=8 m.

=

7Ã¢â‚¬â€œ50. If L = 9 m, the beam will fail when the maximum

shear force is Vmax 5 kN or the maximum bending

moment is M max 2 kNÃ¢â‚¬Â¢m. Determine the magnitude Mo

of the largest couple moments it will support.
