1. The problem statement, all variables and given/known data An elevator cable can stand a maximum tension of 19000N before breaking. The elevator has a mass of 520 kg, and a maximum acceleration of 2.16 m/s^2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaking tension. How many 65-kg people can the elevator safely accomodate? round down to the nearest integer 2. Relevant equations ma=T-mg 3. The attempt at a solution Ok so this is what I did, I tried to come up with an equation for the total mass the elevator can handle ma=T-mg T=mg +ma m=T/(g+a) T= (2/3)(19,000N)= 126667.67 g=9.8m/s^2 a=2.16m/s^2 So i plugged everything in: m= [(12,6667.67)/(9.8+2.16)] / 65.0kg and it came out to be around 16.3 kg, which i rounded down to 16 people, and apparently this answer is wrong. Can anyone help me out?
