42.

The horizontal reaction at the support A of the structure shown in below figure, is

 [A]. zero [B]. 1 t [C]. 2 t [D]. 3 t [E]. 2.5 t.

Explanation:

No answer description available for this question.

 Wazeer Baloch said: (Apr 25, 2017) It should be 3t.

 Khan said: (May 14, 2017) Yes, it is 3.

 Aarv said: (Aug 9, 2017) Please explain.

 Pavan @ RGUKT said: (Oct 23, 2019) How will be 3?

 Chakradhar said: (Jun 6, 2020) Vertical reaction : 3t. Here, it is asked about the horizontal reaction : 0.

 Hamza Cheema said: (Aug 28, 2020) It should be 2t.

 Hamza Cheema said: (Aug 28, 2020) Yes, horizontal reaction is zero, you can check it by taking moment at B.

 Ihsan Khan said: (Oct 15, 2020) How is it possible? A should resist some of the horizontal load. It should be 1t.

 Engr Hilal Wazir said: (Mar 19, 2021) I think the correct answer is 2t because 2t load is applied on the object at the right direction so balancing load will be applied at A in the left direction.

 Mesbah Ullah said: (Oct 5, 2021) The answer is right because the support at B is showing resistance in x and why direction. If you resolve the normal at B into Nsin45 and Ncos45 then 2t horizontal force is taken by Nsin45 component and horizontal at A will become zero.
