Question

A stick is placed on steps as shown in figure. Draw normal forces on the stick
​

Answer 1

Answer:

As Normal is the reaction contact force which acts when there is some action force and Hence the Normal reaction force should be equal to the weight of the rod which is downward. In this situation the normal is not a operating on a single one but it is operating on 2 points in contact with the staircase.

Explanation:

N2 is slightly tilted towards N1 and N1 is straight and perpendicular to the staircase.
