- (Heat transfer) The formula developed in Exercise 5 can be used to determine the cooling time, t, caused only by radiation, of each planet in the solar system. For convenience, this formula is repeated here (see Exercise 5 for a definition of each symbol): t=Nk2eAT3fin A=surfaceareaofasphere=4r2 N=numberofatoms=volumeofthespherevolumeofanatom Volume of a sphere sphere=43radius3 The volume of a single atom is approximately 11029m3 . Using this information and the current temperatures and radii listed in the following chart, determine the time it took each planet to cool to its current temperature, caused only by radiation.arrow_forward(Thermodynamics) The work, W, performed by a single piston in an engine can be determined by this formula: W=Fd F is the force provided by the piston in Newtons. d is the distance the piston moves in meters. a. Determine the units of W by calculating the units resulting from the right side of the formula. Check that your answer corresponds to the units for work listed in Table 1.1. b. Determine the work performed by a piston that provides a force of 1000 N over a distance of 15 centimeters.arrow_forward(Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft). Eisthemodulesofelasticity( lbs/f t 2 ).Iisthesecondmomentofinertia( f t 4 ). For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ftarrow_forward
- (Statics) An annulus is a cylindrical rod with a hollow center, as shown in Figure 6.7. Its second moment of inertia is given by this formula: I4(r24r14) I is the second moment of inertia (m4). r2 is the outer radius (m). r1 is the inner radius (m). a. Using this formula, write a function called annulusMoment ( ) that accepts two double-precision numbers as parameters (one for the outer radius and one for the inner radius), calculates the corresponding second moment of inertia, and displays the result. b. Include the function written in Exercise 5a in a working program. Make sure your function is called from main(). Test the function by passing various data to it.arrow_forward(Automotive) a. An automobile engine’s performance can be determined by monitoring its rotations per minute (rpm). Determine the conversion factors that can be used to convert rpm to frequency in hertz (Hz), given that 1rotation=1cycle,1minute=60seconds,and1Hz=1cycle/sec. b. Using the conversion factors you determined in Exercise 7a, convert 2000 rpm into hertz.arrow_forward(Desk check) Determine the value in total after each of the following loops is executed: a.total=0;for( i=1;i=10;i=i+1)total=total+1;b.total=1;for( count=1;count=10;count=count+1)total=total2;c.total=0;for( i=10;i=15;i=i+1)total=total+i;d.total=50;for( i=1;i=10;i=i+1)total=totali;e.total=1;for( icnt=1;icnt=8;++icnt)total=totalicnt;f.total=1.0;for( j=1;j=5;++j)total=total/2.0;arrow_forward
- (Conversion) Blood pressure is the force of blood circulating against the inner wall of blood vessels. It’s measured by two numbers: a systolic number that measures the pressure when the heart is contracting and a diastolic number that measures the pressure when the heart is resting. Both pressures are typically measured in millimeters of mercury (mm Hg) and given assystolic/diastolic numbers, such as 122/88. The National Heart, Blood, and Lung Institute provides the following guidelines for normal and high blood pressure measurements. Complete the chart by converting the measurements to atm and psi units.arrow_forwardDrag and drop the proper termsarrow_forwardFind the values, if any, of the Boolean variable x that satisfy these equations. a) x · 1 = 0 b) x + x = 0c) x · 1 = x d) x · ??̅ = 1arrow_forward
