QUESTION 3A Type I offshore life jacket (i.e. personal flotation device) is the type worn by commercial fishermen - it isdesigned for extended survival in rough, open seawater. Consider such a life jacket that uses an impermeablefoam material with a density of 32 kg/m³ - the other parts of the life jacket (straps, fasteners, etc) weigh 0.6 kgand are of negligible volume to the design.a) Draw a free body force diagram for the life jacket.b) Determine the minimum volume of foam material (in L) that is needed for the life jacket in order toprovide a minimum 98 N net upward force when it is fully submerged in seawater (as required by USCoast Guard regulations).

The force acting on the life jacket Fnet = 98 N Density of Material ρ =32 kg/m3 The mass of foam…

Concept explainers

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC. Assume that no gas escapes from the balloon during the flight. What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.

A balloon is surrounded by a tank of liquid at negative pressure and is con- nected to the atmosphere by a tube of length L and cross-sectional area A (Fig. 7.25). The pressure inside the balloon p oscillates above and below atmospheric pressure causing small changes in the balloon volume V. The elasticity of the balloon is characterized by its compliance C, defined by Ap = AV/C (a) Derive a second-order differential equation for AV(t), assuming that (i) the pressure differential along the tube accelerates the air in the tube and is not used to overcome entrance, exit, or tube losses; and (ii) the air density p is constant. From the equation, show that the natural frequency of the system is JA/pLC.
