Estimate the deflection at midspan of the truss in Figure treating it as a beam of constant crosssection.
The area of both the top and bottom chords is 10 E = 29,000 ldps/in2. The distance between the centroids of the top and bottom chords equals 9 ft.
suppose you are planning a trip in which a spacecraft is to travel at a constant velocity for exactlyseven months as
Suggest how you would go about validating a password protection system for an application that you have developed. Explain the function of any tools that you think may be useful.
If the cost of heat loss rises by $200 per year (uniform gradient) after the next year and the owner plans to keep the present building for 15 more years, what would you recommend if the interest rate is 10% per year?
