Question : 172 of 200

Marks: +1, -0

A downward vertical load of 10 kN acts at a distance of 40 cm from the left end on a 1 m long beam. This beam is simply supported at both ends. The vertical reaction at the left end is:

0.25 kN
5 kN
6 kN
4 kN

Validate

Solution:

Let

R_{A}

and

R_{B}

be the reactions at points

A

and

B

respectively.
Balancing the moment about point B.

\∑{M}_{{B}}=0

{R}_{{A}} \×100=10 \×60

{R}_{{A}}=6 {kN}
