Block A weighs 200 Ibs and wedge B weighs 20 Ibs. The angle of friction is 20° for all contact
surfaces.
A
F
B
20°
QID:(573211113.112112422)
Using a FBD for each block, find the magnitude of the friction forces resisting motion at all three
surfaces. Then find the value of F to just start wedge B to the right.
a. Friction between A and wall: 72.8
x 87.9 Ib
Friction between A and B: 489
X o 129 Ib
Friction between B and floor: 421
x o 112 Ib
b. F = 171
x 354 Ib
