2008 NEW FACES IN ENGINEERING CALL FOR NOMINATIONS
NSPE is seeking nominations of dynamic, young engineers for the 2008 New Faces
of Engineering, a recognition program sponsored by Engineers Week. The
initiative promotes the accomplishments of young engineers by highlighting their
engineering contributions and their impact on society.
Individuals selected from the various engineering societies will be featured in
a full-page advertisement in USA Today during Engineers Week (February 17-23,
2008). Each photo will be captioned with the engineer's name, the name of the
engineering society providing the nominee, the employer, and a brief statement
of that individual's accomplishments as they relate to the public welfare.
Circulation will include not only USA Today but also the engineering trade
press, the individual's local press, and the Web sites of Engineers Week and the
sponsoring engineering societies, among others. Learn more about Engineers Week
(http://www.eweek.org).
THE DEADLINE FOR SUBMISSION IS FRIDAY, NOVEMBER 9, 2007
If you know an NSPE member that is an engineer intern or licensed working
engineer two to five years out of college or graduate school who could represent
the up-and-coming in the profession, nominate them now! Nomination applications
can be found on the NSPE website (http://www.nspe.org/awards/aw1-newfaces.asp)
MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Homerun Record
Hank Aaron held the National League homerun record for 33 years. During his 23
season career with Major League Baseball, he hit 755 homeruns. On August 7th,
2007, Barry Bonds broke that record by hitting his 756th homerun in a game
against the Nationals.
Barry Bonds is in his 21st season with Major League Baseball. If he ends this
season with 760 career homeruns and continues this homerun/year average
throughout the rest of his career, how many homeruns will he hit by the end of
his 23rd season? Express your answer to the nearest whole number.
--------------------------------------------------------------------------------
Assuming Barry Bonds ends this season with 760 career homeruns, what percent
greater is his homerun/year average than Hank Aaron’s homerun/year average?
Express your answer to the nearest tenth.
--------------------------------------------------------------------------------
The lucky (or unlucky, depending on your view) fan who caught Barry Bonds’
record-setting ball may have to pay 35% in taxes on the estimated value of the
ball. If the IRS tells the fan that he owes $250,000 in taxes for the ball, how
much did the IRS estimate the ball to be worth?
Answer to last week’s MATHCOUNTS problem:
1000 pounds ×
(454 grams/1 pound) × (1 foot3/ 7 grams) = 64,857 feet3.
So 64,857 feet3 of heated air are needed in the envelope of the
balloon to lift 1000 pounds.
--------------------------------------------------------------------------------
The formula for the
volume of a sphere is four-thirds times pi times the radius cubed. 64,857 =
(4/3)πr3. Solving for
r,
r = 24.92 feet. Diameter = 2 ×
24.92 = 49.84. The diameter of the sphere that will lift 1000 pounds is 50
feet.
--------------------------------------------------------------------------------
Let
y represent the altitude and
x represent time. The initial
altitude is 1200 feet. The equation in slope intercept form that models the
altitude as a function of time is y
= −20x + 1200. Use the equation
with y = 0. Solve for
x.
x = 60 minutes. The expected time
for the altitude to be 0 is 10:05 a.m.
