Homework Help Overview

The discussion revolves around a physics problem involving three connected masses on an inclined plane, focusing on equilibrium conditions and the effects of friction. Participants are tasked with determining various quantities such as mass, tensions, and acceleration under different scenarios.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants attempt to derive expressions for mass and tensions based on equilibrium conditions and forces acting on the system. Some express uncertainty about the correctness of their answers, while others highlight the difficulty in verifying solutions without a visual representation of the problem.

Discussion Status

The discussion is ongoing, with participants seeking validation for their derived answers. There is a recognition of the complexity of the problem, and some participants are questioning the adequacy of the information provided to check the work effectively.

Contextual Notes

Participants note the absence of a diagram or detailed description of the arrangement, which complicates the verification of solutions and understanding of the problem setup.

Homework Statement


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

Homework Equations


F=ma
Efy=0
Efx=0

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) don't 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.
