a disk with mass m rests on an inclined surface for which ������ =0.2. determine the maximum vertical force p that may be applied to link ab without causing the disk to slip at c.

total distance/total time

(85 + 82)/(5+3)

20 just over

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
