You stand on a bathroom scale that rests on the floor of anelevator. (Don't ask why!) Standing on the scale compressesinternal springs and activates a dial that indicates your weight innewtons. When the elevator is at rest, the scale reads 600 N. Thenthe elevator begins to move upward with a constant acceleration of2.00 m/s/s.Determine your true mass.Determine the scale reading while the elevator isaccelerating.If you read the scale without realizing that it is acceleratingupward what might you think your mass is?What would your answers be if the elevator is acceleratingdownward?
A bus has helper springs with k1= 1x10^5(#/ft) and regular leaf springs that have k2= 0.6x10^5(#/ft). I place a load of 16,000# on those springs. (a) If there is no free space between the leaf and the air helper spring, how far will the leaf springs displace downward with this load? (b) How far down, under the same circumstances, would the air-bag overload spring compress?
