Homework Help Overview

The problem involves calculating the maximum mass that an elevator can support given a maximum tension in the cable of 10kN and an acceleration of 2m/s². The context is within the subject area of dynamics and forces.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss using Newton's second law (F = ma) to relate force, mass, and acceleration. Some express difficulty in applying the formula correctly, while others suggest identifying the forces acting on the elevator.

Discussion Status

The discussion is ongoing, with some participants providing guidance on using the fundamental physics principles. Multiple interpretations of the problem setup and calculations are being explored, but no consensus has been reached yet.

Contextual Notes

There is mention of multiple choice answers provided by one participant, indicating a structured approach to the problem, but the relevance of these options is still under discussion.

Homework Statement



An elevator cable can hold a maximum of 10kN and has a maximum accelleration of 2m/s2. Determine the maximum mass of the elevator and participants.


i need some help, can't figure this out at all. thanks in advance
 
Physics news on Phys.org
The obvious thing here is to use F = ma
You know F and you know a... find m.
If you get stuck get back to me
 
I tryed putting them just straight in but that does not work.

I forgot to put the multiple choice, it might help

A. 1050kg
B. 1280kg
C. 0.8466kg
D. 1.28kg
E. 890kg
F. 10009.81kg
G. 846.74kg
H. 9.901kg
I. 650kg
 
Identify the magnitude and direction of the forces acting on the elevator, both known and unknown. There are 2 forces acting in the vertical direction. Find the net force, and use Newton's 2nd law, F_net = ma.
