An elevator (mass 4700 kg) is to be designed so that the maximum acceleration is 6.00×10^-2 g

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?

• Physics -

forcemax=mass*amax=4700(.06+1)g

force min=mass*g that is the force to hold the elevator still.

• Physics -

I've tried both of those. Does not work.

• Physics -

ma = tension - weight so ma + weight = tension so 4700(.06)(9.8) + 4700(9.8)
