2) vertical component of reaction force
3) Resultant of normal reaction and reaction force
4) None of the above

please answer this
​

Answer 1

3) Resultant of normal reaction and reaction force

Answer 2

Answer:

hope it's helps you army

Explanation:

1) The horizontal component can be resisted only by the reaction at A since the support at B is a roller support. ... The reaction at A is a single force; Ax and Ay represent the components of that one force. If we do not know the direction of the force, we must assume a direction.

2) The vertical component of the ground reaction force acts straight through the joint; therefore, this will not produce a moment. The horizontal component acts to the right and below the ankle.

3) Answer. Answer: No, angle of friction is the angle between normal reaction and the resultant of normal reaction and frictional force. Also, the angle between friction and normal reaction is always 90 degree as friction is always along the surface and normal is always perpendicular to the surface.

4) None of the above", or NOTA for short, also known as "against all" or a "scratch" vote, is a ballot option in some jurisdictions or organizations, designed to allow the voter to indicate disapproval of the candidates in a voting system
