Homework Help: torque problem!

Posted by Cecilia on Saturday, November 8, 2008 at 5:40pm.

A spring (k =819N/m) is hanging from the ceiling of an elevator, and a 5.1-kg object is attached to the lower end. By how much does the spring stretch (relative to its unstrained length) when the elevator is accelerating upward at a = 0.46m/s^2?

Torque? How do you think that?

forceonspring=kx=m(a+g)
x=1/k (m(acceleration +g)
solve for x
