When I was considering what to do with my $10,000 Lottery winnings, my broker suggested I invest half of it in gold, the value of which was growing by 11% per year, and the other half in certificates of deposit (CDs), which were yielding 2% per year, compounded every 6 months. Assuming that these rates are sustained, how much will my investment be worth in 9 years? (Round your answer to the nearest cent.)
a link in a mechanism is to be subjected to a tensile force that varies from 3500 to 500 N in cyclical fashion a the mechanism runs. It has been decided to use AISI 1040 cold drawn steel. Complete the design of the link, specifying a suitable cros..
