1.A water tank is completely filled with liquid water at 20 degree Celcius. The tank material is such that it can withsatand tension caused by a volume expansion of 2%. Determine the max temperature rise in Celcius degress allowed without jeopardizing safety. Neglet the effect of pressure change.
2.Determine the resultant pf the following coplanar system of forces:261lbs.,10 degrees ''39lbs.114 degrees;63lbs.,183 degrees;57lbs.,261 degrees.
3.A tow truck is using a cable to pull a car up a 15 degree hill. If the car weighs 4000 lbs and the cable has a diameter of .75 inches, find the stress in the cable when the truck comes to a stop while on the hill. Ignore friction between the car and the pavement.
the pressure ratio across the compressor is 9 and the maximum temperature is 827c.the turbine and comprssor processes are adiabatic with turbine efficiency of 90% and a compressor efficiency of 85%.
Cylinders A & B weigh 500N each and cylinder C weighs 1000N. Assuming frictionless contact between all surfaces, find all contact forces. Diameters A&B= 1, C=2. Frictionless contact means forces are normal to the contacting surfaces.
Determine the maximum and minimum stress intensities in the section.
The partial pressure of the gasses in a 22,414-L volume of air at STP are: oxygen, 21,224 kPa; nitrogen, 79,119 kPa; argon, 0.946 kPa; and carbondioxide, 0.036 kPa. Determine the gram molecular weight of air.
a room having a total heat gain of 35,000 btuh is to be maintained at 80 DB and 62 WB. the air is supplied to the room at 60 DB and 55 WB. find the quanity of air to be supplied.
For some minerals color is a diagnostic property making identification rather easy. However, certain minerals can also occur in a wide variety of colors making color a poor tool for identification. List different colors for the mineral quartz lo..
If the brakes are applied uniformly for 5 sec to bring the rig to a stop from a speed of 20 mph while moving down a 10 percent grade, determine the force P in the coupling between the trailer and the truck. The truck weighs 20,000 lbf and the trai..
determine the horizontal spacing of the vertical drains if the drains are installed in triangular grid to reach 90% of primary consolidation in 1.5 years after the commencement of fill placement
Polychloroprene is an amorphous polymer used in o-rings due to its excellent chemical resistance and has recently been used as an iPod holder. It is known by the trade name neoprene.
The rod is fixed against rotation at its left end, but free to rotate in a bearing at its right end. Each disk is 300mm in diameter. Calculate the maximum shear stress in each segment of the rod.
The in-situ bulk density of the sandy silt is 1.92 Mg/m^3 and its average water content is 13%. determine: a) the total volume of the sandy silt that must be removed from the borrow pit for construction of the embankment
