Question: Block A has mass mA and rests on surface B for which the coefficient of static friction is sAB. If the coefficient of static friction

Block A has mass mA and rests on surface B for which the coefficient of static friction is μsAB. If the coefficient of static friction between the cord and the fixed peg at C is μsC, determine the greatest mass mD of the suspended cylinder D without causing motion.

Given:

mA = 50 kg

μsAB = 0.25

μ sC = 0.3

a = 0.3 m

b = 0.25 m

c = 0.4 m

d = 3

f = 4

g = 9.81m/s2
