Answer 2

The number of reactions at roller support is 1. (option a)

• Roller support is a type of support that allows translation, or motion in the horizontal direction parallel to the surface on which it rests, and rotation about the support. But the roller support resists the motion of the body in the vertical direction.
• Since the reaction is opposite to the load being applied by the object when the support offers some resistance, there will not be any reaction in the horizontal direction, and against rotation.
• So, the only reaction by the roller support will be in the vertical direction.
