Question
3) A mass, m2 = 40 kg is pulling up another mass, m1, via a pulley as shown:
my
The ramp is inclined at an angle, 0 = 30°. The coefficient of static friction of the ramp is 0.4,
and the coefficient of kinetic friction of the ramp is 0.2,
a) What is the maximum value of mass, m1, so that mass, m2, begins to move
down the inclined plane?
т
what is the value of m1 ?
b) If mass, m2, accelerates down the ramp at a rate of 1"/2
