Σy = 0
⇒ R_o sin 36.87 – 90 = 0

Horizontal reaction at O = H_o
= R_o cos 36.87 = 150 × cos 36.87
= 120 kN

Similar GATE Doubts

A rigid, uniform, weightless, horizontal bar is connected to three vertical members P, Q and R as shown in the figure (not drawn to the scal e). All three members have identical axial stiffness of 10 kN/mm. The lower ends of bars P and R rest on a rigid horizontal surface. When NO load is applied, a gap of 2 mm exists between the lower end of the bar Q and the rigid horizontal surface. When a vertical load W is placed on the horizontal bar in the downward direction, the bar still remains horizontal and gets displaced by 5 mm in the vertically downward direction.The magnitude of the load W (in kN, round off to the nearest integer), is ______. Correct answer is '130'. Can you explain this answer?
