The refrigerator has a weight of 200 lb and a center of gravity at G. Determine the force P required to move it. Will the refrigerator tip or slip? Take = 0.4.

The refrigerator has a weight of 200 lb and a center of gravity at G. Determine the force P required to move it. Will the refrigerator tip or slip? Take  = 0.4.

Solution

 tan (theta) = (meu_k) = 1.5/h; (meu_k) = 0.4.

0.4 = 1.5/h ; h = 3.75.

Where h = 4 (meu_k) = 1.5/4 = 0.375.

Then at (meu_k) = 0.4 the refrigeration is tips.

And at (meu_k) = 0.375 the refrigeration is slips.

Sum moments about other end equal to zero.

P*4-(200*1.5) = 0; p = 200*1.5/4; p = 75 lb tips.
