# A refrigerator of width w and height h rests on a rough incline as in Figure P8.31. Find an expression for the maximum value θ can have before the refrigerator tips over. Note, the contact point between the refrigerator and incline shifts as θ increases and treat the refrigerator as a uniform box.Figure P8.31

To determine
The maximum value of θ .

Explanation

The free body diagram is,

When the refrigerator is about to tip off the surface, the direction of weight is along the edge about which it rotates. The corresponding angle will be the maximum value of Î¸ .

Therefore,

tanÎ¸max=(w/2)(h
