Consider the 6 m long beam subjected to the loading shown. Ground reactions and the shear-force diagram are also presented. The maximum value of the positive moment M is most closely equal to 25 kN-m 47.5 kN 47.5 Units: KN 50.2 kN-m 58.7 kN-m 65.6 kN-m 46.8 kN-m 40.5 KN-m 15 kN/m 6 m @x=3.167 m 10 kN-m 42.5 KN -42.5 X
