An elevator mass 4950 kg is to be designed so that the maximum acceleration is 6.10×10-2g.
What is the maximum force the motor should exert on the supporting cable?
What is the minimum force the motor should exert on the supporting cable?
[tex]\Sigma[\tex]F = ma
The Attempt at a Solution
I know this should be so easy, but Mastering Physics is not liking my answers. I have tried multiplying the combined forces of acceleration and gravity multiplied over the mass to get a large force, that answer was incorrect. I noticed that the units of acceleration is in 'g', which caused me to believe they were referencing that amount multiplied by gravity instead of added to it, which resulted in another answer MP did not like. My results:
F = 48800 N
F = 2960 N
Three significant figures, neither of those answers were correct (this is for Fmax). I am afraid I am missing something really critical, and wanted to get another opinion. Maybe I'm approaching this problem in the wrong way?
