### Problem 11.83

A garage door is mounted on an overhead rail (illustrated in the figure below). The wheels at point A and point B have rusted in such a way that they no longer roll but instead slide along the track. The coefficient of kinetic friction is \(0.51\). The distance between the wheels is \(2.00 \, \text{m}\), with each wheel positioned \(0.50 \, \text{m}\) from the vertical sides of the door. The door is uniformly weighted and it weighs \(625 \, \text{N}\). It is being pushed to the left at a constant speed by a horizontal force \( \mathbf{F} \).

#### Figure:
The figure depicts a simplified diagram of the garage door.  
- The door is rectangular, with a width of \(3.00 \, \text{m}\).  
- There are two wheels, labeled \(A\) and \(B\), which are positioned \(2.00 \, \text{m}\) apart.  
- A horizontal force \( \mathbf{F} \) is applied to the door at a height \( h \) above the ground, pushing the door to the left.

#### Part A
If the distance \( h \) is \(1.58 \, \text{m}\), what is the vertical component of the force exerted on the wheel \(A\) by the track?

\[ F_{A} = \quad \text{N} \]

#### Part B
If the distance \( h \) is \(1.58 \, \text{m}\), what is the vertical component of the force exerted on the wheel \(B\) by the track?

\[ F_{B} = \quad \text{N} \]

#### Part C
Determine the maximum value that \( h \) can have without causing one wheel to leave the track.

\[ h_{\text{max}} = \quad \text{m} \]
