Block A rests on the surface for which the coefficient of friction is sAB. If the mass

Block A rests on the surface for which the coefficient of friction is μsAB. If the mass of the suspended cylinder is mD, determine the smallest mass mA of block A so that it does not slip or tip. The coefficient of static friction between the cord and the fixed peg at C is μsC.

Units Used:

g = 9.81m/s2

Given:

μsAB = 0.25

mD = 4 kg

μsC = 0.3

a = 0.3 m

b = 0.25 m

c = 0.4 m

d = 3

f = 4
