2.A tank measuring 10 feet by 10 feet by 10 feet is completely filled with water. If a 4-inch diameter, square edged orifice is located 1 foot above the bottom of the tank (to orifice center) what is the discharge? a).0.2 cfs b).1.3 cfs c).3.1 cfs d).5.3 cfs
3.Springs AB and CD have a stiffness of k = 300 N/m and k' = 200 N/m, respectively, and both springs have an unstretched length of 600 mm. If the 2-kg smooth collar starts from rest when the springs are unstretched, determine the speed of the collar when it has moved 200 mm.
4.Explain how medical technologies and the pharmaceutical industry are driving healthcare service demands and costs? What are the cost/benefits of this trend?
At an axial load of 23 kN, a 40-mm-wide by 10-mm-thick polyimide polymer bar elongates 2.7 mm while the bar width contracts 0.17 mm. The bar is 240 mm long. At the 23-kN load, the stress in the polymer bar is less than its proportional limit.
