Question

300 mm 4. (5 pts) If the coefficients of friction and the weights of blocks A 400 mm and B are known and horizontal width of block A is excessively large compared to the height, determine how many cases of impending motion would need to be considered in order to determine what will happen if P is large enough to cause the loss of static equilibrium for the system shown. Assume that the coefficients of friction are such that multiple impending motion conditions will not occur at the same time. ??? HA A. B. C. D. E.

Explanation / Answer

3 caes to analyze

1.) Both blocks moving together.

2.) Top block moving and bottom block at rest

3.) Bottom block at rest. Top block toppling.
