1.A circuit to detect a signed arithmetic overflow for a 8-bit system is (S8 AND (NOT A8) AND (NOT B8) OR (NOT S8) AND A8 AND B8). Briefly explain if this is correct and why
2.The basic barometer can be used to measure the height of abuilding. If the barometric readings at the top and at the bottomof a building are 28.7 and 29.7 in Hg, respectively, determine the height of the building in feet. Assume an average density of air of 0.0737lbm/ft^3.
3.How do you determine the neutral axis angle given x and y deflection measurements and load applied (mm)? Please include a worked example.
A tubular aluminium bar (G=28GPa) of square cross section with outer dimensions 50mm x 50mm must resist a torque T=300Nm. Calculate the minimum required wall thickness t_min if allowbale shear stress is 20MPa
A steel railroad track (Es=200 GPA, as=11.7x10-6/oC) was laid out at a temperature of 6/oC. Determine the normal stress in the rails when the temperature reaches 48oC assuming that the rails (a) are welded to form a continuous track (b) are 10m long ..
A steel cylinder tank is 10 ft in diameter, 15 ft high, and is filled with a brine solution. Brine weighs 10 lbf/gal. The thickness of the steel shell is 1/2 in. The cylinder sits on a concrete pad 12ft x 12ft .
what is the reason for the relatively high strength of wood in the longitudinal direction of the tree trunk as compared to the transverse direction
Find e1, e2, e3 and deflections at those points
A 1000ft long steel pipe carries water from areservoir with a water elevation at 826ft. The pipe has a diameterof 12in. with a wall thickness of 0.5in.
It is not uncommon to borrow $100,000 or more to purchase a home. Banks typically offer 15-,20-, and 30- year loans. a) Calculate the monthly loan payment to repay a $100,000 home loan
A piston-cylinder device contains helium gas initially at 150 kPa, 20 degrees C, and 0.5 m^3. The helium is now compressed in a polytropic process (PV^n = constant) to 400 kPa and 140 degrees C. Determine the heat loss or gain during this process.
A chlorination process is to be used to disinfect a wastewater treatment plant effluent. The plant treats 1.8MGD (million gallon per day). The water entering this unit has about 4500mg/L of coliforms, and the effluent target is 0.1 mg/L of coliforms.
The truck is driving onto the stationary barge at the speed of v1. The masses of the truck and the barge are m and M, respectively. The barge is free to move on the water and the water resistance is to be ignored.
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).
A temporary flood wall has been constructed to protect several homes in the floodplain. the wall was built to withstand any discharge up to the 20-year period after all the homes have been relocated.
