Multiple-Concept Example presents a model for solving this problem. As far as vertical oscillations are concerned, a certain automobile can be considered to be mounted on four identical springs, each having a spring constant of 1.30 × 105 N/m. Four identical passengers sit down inside the car, and it is set into a vertical oscillation that has a period of 0.370 s. If the mass of the empty car is 1560 kg, determine the mass of each passenger. Assume that the mass of the car and its passengers is distributed evenly over the springs.

Recap Corporation made a capital investment of $ 100,000 in new equipment 2 years ago. The analysis made at that time indicated that the equipment would save $36,400 in operating expenses per year over a 5-year period, or a 24% return on capital before taxes per year based on the internal rate of...
A random sample of size n1 = 25 taken from a normal population with a standard deviation < ?1 = 5 has a mean 1 = 80. A second random sample of size n2 = 36, taken from a different normal population with a standard deviation ?2 = 3, has a mean 2 = 75. Find a 94% confidence interval for µ1 - µ2.

An 8.0-kg stone at the end of a steel wire is being whirled in a circle at a constant tangential speed of 12 m/s. The stone is moving on the surface of a frictionless horizontal table. The wire is 4.0 m long and has a radius of 1.0 × 10-3 m. Find the strain in the wire.
Repeat Problem 11.24, but assume a closed instead of an open feedwater heater. A single pump is used to pump the water leaving the condenser up to the boiler pressure of 3.5 MPa. Condensate from the feedwater heater is drained through a trap to the condenser.
