Tension and Acceleration in a Pulley System

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving two packing crates connected by a string over a frictionless pulley. The crates have different masses, and one is on an incline. The objective is to determine the acceleration of the crate on the incline and the tension in the string.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the forces acting on the crate on the incline and the implications of tension in the system. Questions are raised about the specific forces at play and how to set up the equations of motion.

Discussion Status

The conversation is ongoing, with participants sharing insights about the forces involved and the nature of tension. Some guidance has been offered regarding the direction of tension and the role of weight, but no consensus has been reached on how to proceed with the calculations.

Contextual Notes

Participants note that the original poster is relatively new to the concept of tension in physics problems, which may influence their understanding and approach to the problem.

Homework Statement



Two packing crates of masses m1 = 10.0 kg and m2 = 5.00 kg are connected by a light string that passes over a frictionless pulley . The 5.00 kg crate lies on a smooth incline of angle 40.0°. Find the acceleration of the 5.00 kg crate and the tension in the string.


Homework Equations



i know there is only 1 tension because they area attached by a frictionless string, i just don't know where to go from there

The Attempt at a Solution



 
Physics news on Phys.org
What are the forces acting on the 5 kg block on the incline?
 
i told of everything the question gave me for info
 
Like, what forces act on the crate placed on the smooth incline?
Write the force equations and calculate.
 
thats where i am stuck...I'm kinda new to this tension stuff
 
Ok, you must have read that tension always acts away from the body. The weight of the body will also have an effect on its motion, in this case. Keeping these points in mind, work out the possibilities and inform us of the developments.
