PRACTICAL STRUCTURAL DESIGN 



Fig. 32 Graphical Method for Concentrated Load with Wide Bearing 



Studying Fig. 33 we see that the reactions are as follows: 



750 x 25 



HI = = 9o7.5 IDS. 



^U 



R 2 = 750 - 937.5 = -187.5 Ibs. 



The weight of the beam has been neglected and the load at the 

 extreme left tends to revolve the beam around Ri so an additional 



R 2 I875 



R- +9575 

 Fig. 33 Concentrated Load on Short Overhanging Beam 



load of 187.5 Ibs. will be required at -R 2 to hold down the right 

 end. The negative sign indicates an upward pull.
