36.A truss hinged at one end, supported on rollers at the
other, is subjected to the
horizontals load only. It’s reaction at the hinged end will be
A) horizontal
B) vertical
C) resultant of horizontal and vertical

In a truss that is hinged at one end and supported on rollers at the other, the hinge can provide support in both horizontal and vertical directions. However, in this specific case where the truss is subjected to horizontal loads only, the hinge will primarily react with a horizontal force to balance the applied load. Any vertical reaction force at the hinge would be zero since there’s no vertical load acting on the truss.

The roller support, on the other hand, will allow vertical movement and will only provide vertical support. Thus, the correct answer focuses solely on the horizontal reaction at the hinge, confirming that it primarily provides a horizontal reaction.
