Direction: A simply supported beam PQ is subjected to a load of 100 kN through a rigid link at the centre of the beam as shown in the figure below 
-
Correct shear force diagram for the beam is
Correct Option: A
Taking moment about Q of all the forces and equate it to zero.
RP x 10 = 10 ; RP = 1 kN(↑) and RQ = 1 kN (↓)
