A single bolted double cover butt joint is used to connect two plates which are 8 mm thick. Assuming 16 mm diameter bolts of grade 4.6 and cover plates to be 6 mm thick. Calculate the efficiency of the joint, if four bolts are provided in the bolt line at a pitch of 45 mm. Assume grade of steel Fe410, kb = 0.55 & thread intercept shear plane.
Consider a Carnot-cycle heat pump with R-410a as the working fluid. Heat is rejected from the R-410a at 110 F, during which process the R-410a changes from saturated vapor to saturated liquid. The heat is transferred to the R-410a at 30 F.
A carbon steel tank, 6ft. inside diameter X 10 ft. long with a 3/8 inch wall, is sitting on evenly spaced rolls and 4 evenly spaced supports (2 on each side). What is the horizontal force excerted on the supports? From the detail provided
Determine the volume of water lost (in m3) through evaporation during a year from Lake Okeechobee (Florida). Lake Okeechobee has a surface area of 190,000-ha located in a region where the annual rainfall is 1500 mm. The increase in the depth of the l..
At the end of 15 years, the first motor will have a salvage value of $50 and the second motor will have a salvage value of $100. consider the MARR to be 8%. (note : 1HP=0.7457 kw). Determine which motor should be installed based on the PW criterio..
A coal with 6% ash and a heating value of 13,000 Btu/lb is burned in a new power plant. Assume that 30% of the ask falls out as bottom ash in the furnace. Calculate the efficiency of ESP required to meet federal new source performance standards.
Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured g/m^3. Assume that a cumulus cloud occupies a volume of one cubic km, and its liquid water content is 0.2g/m^3.
Determine the bending moments produced at the joints of the rigidly jointed frame shown in Figure S7.7by the indicated loads. The relative EI / L values are shown ringed alongside the members.
a ball is thrown with a valocity of 30 m/s at an angle of 40 degrees above the horizontal from the top of a 100m tall building. what is balls velocity when it lands. (neglect air resistance in both cases) DO NOT USE 2D projectile motions, only work ..
develop a simple urban constructed wetland design guidelines and drawings. your report should include the followingi.
A steam power plant has 1200 F in the boiler, 630 Btu/s work out of the turbine, 900 Btu/s is taken out at 100 F in the condenser, and the pump work is 30 Btu/s. Find the plant's thermal effi- ciency. Assuming the same pump work and heat transfer ..
You open a 16 oz (1 pint) bottle of a carbonated soft drink that has a temperature of 5°C, then you get distracted and forget to drink it. You come back quite some time later and find that it has gone "flat," and that it has gotten warm (20°C).
Part B (Assignment): by trial and error, find the angle that will give the minimum force F to make a basket (hint: try 52 degrees)The trajectory of the ball will make a basket when x = L and y = Hb
