Question

Two wheel loads 10 kN and 30 kN space 5 m apart are moving on a over hanging beam as shown in figure. Maximum reaction is

• A. 58 kN
• B. 70 kN
• C. 46 kN
• D. 50 kN

Answer 1

The correct option is B 70 kN

Reaction at 'C' is maximum, because length of overhang is maximum. Draw the ILD for the $R_C$ and place the load on the higher ordinate. We will get the maximum reaction.


$MaximumreactionatC=10\times 1+30\times 2$
$=70kN$
