C Scenario 3 Box begins to tip Now consider the case where t

·C Scenario 3: Box begins to tip. Now, consider the case where the force P causes the box to begin tip. In general, the box will tip if (select one): I The normal force, N, required for equilibrium is not located directly under the weight force, Il b. The applied force, P, is greater than the static friction force, F, resisting it III. c. The normal force, N, required for equilibrium is not located under the box Considering all the previous calculations we can determine whether the box will move. The box will (select one): Not move I Tip over IIl. Slide along the floor

Solution

In general ,the box will tip if the normal force N required for equilibrium is not located under the box. the correct answer for the first question is c. This comes from the fact that if the normal force required for equilibrium is not located under the box, the moment equilibrium of nthe box about the tipping corner is not satisfied,i.e., the moment causing tipping exceeds the moment restoring the box.

For the box to tip over, moment of P about bottom right corner should be just greater than moment of W about the same point.

P*h>W*b/2

or, P>W*b/2h

If the above condistion is satisfied, then the box will tip over

Also, let maxiumum friction force that can be exerted by ground on box be F

For the box to slide, P>F
