They don't ask for the height of the nail, and don't give enough information to compute it if they did ask, but I still stand corrected.haruspex said:
You’re right, there's not enough information for that, which means I misinterpreted "outward" force. I would have banged the nail in pointing up into the wall, but then the question would would make no sense, so I took it to be horizontal. Outward from the wall is then also horizontal, but then you would need to be able to find the height of the nail.Halc said:

A rigid-body equilibrium problem refers to a situation where a rigid body is at rest or in a state of constant motion with no net forces acting on it. This means that the body is not accelerating and all forces acting on it are balanced.
To determine if a rigid body is in equilibrium, the net force and net torque acting on the body must be equal to zero. This can be calculated by summing up all the forces and torques acting on the body and setting them equal to zero.
The conditions for a rigid body to be in equilibrium are that the net force and net torque acting on the body must be equal to zero. Additionally, the body must not be experiencing any linear or rotational acceleration.
To solve a rigid-body equilibrium problem, you must first identify all the forces and torques acting on the body. Then, apply the conditions for equilibrium to set up equations and solve for any unknown forces or angles.
Some common examples of rigid-body equilibrium problems include a book resting on a table, a ladder leaning against a wall, and a bridge supporting the weight of cars. These situations require the forces and torques acting on the bodies to be balanced in order for them to remain in equilibrium.
