Asked by Emily

An elevator (cabin mass 600 kg) is designed for a maximum load of 2700 kg, and to reach a velocity of 3.4 m/s in 5 s. For this scenario, what is the tension the elevator rope has to withstand?

I know I have to multiply the mass by the acceleration. I'm having a hard time deciphering what exactly I need to use. Please help! Thanks

so the maximum load (cabin plus cargo) is 3300 kg

the tension is the force that will accelerate the load to .68 m/s²
this is against gravity

so the tension overcomes gravity (mg) PLUS accelerates the load

t = m g + m a = m (g + a)
...= 3300 (9.81 + .68)
