1. The problem statement, all variables and given/known data
Consider the three connected objects shown in Figure P5.88. Assume first that the inclined plane is friction- less and that the system is in equilibrium. In terms of m, g, and u, find (a) the mass M and (b) the tensions T1 and T2. Now assume that the value of M is double the value found in part (a). Find (c) the acceleration of each object and (d) the tensions T1 and T2. Next, assume that the coefficient of static friction between m and 2m and the inclined plane is ms and that the system is in equilib- rium. Find (e) the maximum value of M and (f) the minimum value of M. (g) Compare the values of T2 when M has its minimum and ma

2. Relevant equations
F=ma
Efy=0
Efx=0

3. The attempt at a solution
(a) 3msin@
( b) T1= 2mgsin@
T2= 3mgsin@
(c) a= 3gsin@
( d) T2= 6mgsin@
T1 = 2mgsin@
(e) 3ms + 2mgsin@/g
(f) dont know what to do but fs less than Us.N

The problem is long and confusing need help

It will be extremely hard to check your work with neither the diagram nor a description of the arrangement.
