SSC JE Civil Engineering 2014 Set 1 Solved Paper

Question : 152 of 200

Marks: +1, -0

For simply supported beam shown in Fig., the magnitude of vertical reaction at ‘B’ is

Solution:

Let reaction at A and B is

V_A

and

V_B

respectively
∑FY = 0;

V_A + V_B

= 30KN -- equation 1
∑MA = 0;

V_B× 3 - 30 × 1 = 0

V_B

=10 KN
Put the value of

V_B

in eq. 1, we get

V_A

= 20KN
