Question

A cylinder weighing $‘W^{\prime }$ is resting on a V-groove as shown in figure. How many forces should be shown in the $FBD$?

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is C $3$

The free body diagram of the cylinder is as shown in figure. Here, W= weight of cylinder and $N_1$ and $N_2$ are the normal reactions between the cylinder and the two inclined walls. So there are three forces.
