Someone wants to study environmental engineering in a European country for 8 years and wants to deposit an amount of money in one of the approved banks for the purpose of paying his annual study expenses, where it is planned that he will withdraw $2000 annually after one year from the date of deposit for a period of five consecutive years, and then withdraw $3000 annually for the remaining period of his studies. Calculate the amount required to be deposited for the purpose of covering the study expenses if you know that the interest rate is 8.5%
Design a typical girder for the floor system shown in the figure below. In addition to the weight of the beam, the dead
load consists of a 5-inch-thick reinforced concrete slab (normal-weight concrete). The live load is 85 psf, and there is a
20-psf partition load. Do not check deflections. Assume that the girder is supporting beams on each side, and assume
that the beams weigh 35 lb / ft. Let all the loads on the girder act as a uniform load (be sure to include the weight of
the beams).
