Question

In the pulley arrangement shown,the pulley p2 is movable.Assuming coefficient of friction between m and surface to μ,the minimum value of M for which m is at rest is A) M=μm/2 B) m=μM/2 C) M=m/2μ D) m=M/2μ pls answer with solution

Answer 1

Answer:

Please send the pic of the system.

Answer 2

Answer:

M=μm/2

Explanation:

f = 2T

and T = Mg

If m be at rest friction will be static

:

f ≤ N

2Mg ≤ μmg⇒  M =(μm)/(2)
