Question
The uniform 20-lb ladder rests on the rough floor for
which the coefficient of static friction is s = 0.45 and
against the smooth wall at B. Determine the horizontal
force P the man must exert on the ladder in order to
cause it to move.
P =
The 5000-N concrete block is adjusted its position
using a 5° wedge under the action of force F. If the
coefficient of static friction between all contacts is
0.3, determine the least force F required to move
the block.
