. Design a bridge to span a small stream. Assume that rigid supports are available on each bank, 3.0 m apart. The bridge is to be 1.0 m wide and carry a uniformly distributed load of 2.4 kN/m2 over its entire area. Design only the deck boards and beams. Use two or more beams of any size from Appendix A–4(b) or others of your own […]

a steam turbine is to operate on a simple regenerative cycle. steam is supplied dry saturated at 40 bar , and is exhausted to a condenser at 0.07 bar . the condensate is pumped to a pressure of 3.5 bar at which it is mixed with bleed steam from the turbine at 3.5 bar. the resulting water which is at saturation temperature is then pumped […]

Instructions: You are required to write a report following proper format and show all derivation of your solutions. PROBLEM STATEMENT:Consider an automobile traveling over a rough road at a speed of v km/hr. The suspension system has a spring constant of 40 kN/m and a damping ratio of 0.1. The road surface varies sinusoidally with an amplitude of Y= 0.04 m and a wavelength of […]

It is desired to find the cetane number of a fuel oil which has a density of 860 kg/m3 and a midpoint boiling temperature of 229°C. When tested in the standard test engine, the fuel is found to have the same ignition characteristics as a mixture of 23% hexadecane and 77% heptamethylnonane. Calculate: (a) Cetane number of fuel. (b) Percent error if cetane index is […]

A 3-year-old is brought to the emergency department having just ingested a large overdose of chlorpropamide, an oral antidiabetic drug. Chlorpropamide is a weak acid with a pKa of 5.0. It is capable of entering most tissues. On physical examination, the heart rate is 110/min, blood pressure 90/50 mm Hg, and respiratory rate 30/min. Which of the following statements about this case of chlorpropamide overdose […]
