Each cable has a cross-sectional area of 100 mm2 and is made of an elastoplastic material for which σY = 345 MPa and E = 200 GPa. A force Q is applied at C to the rigid bar ABC and is gradually increased from 0 to 50 kN and then reduced to zero. Knowing that the cables were initially taut, determine
(a) the maximum stress that occurs in cable BD,
(b) the maximum deflection of point C,
(c) the final displacement of point C
A counter flow cooling tower cools 2000 gal/min water from 104 F to 85 F with 210,000 ft^3/min of air at 90 F Dry bulb Temperature and 76 F WBT . The Mass transfer coefficient -surface area product is hA= 123lbm/hr ft^3. Air mass flow rate per unit c..
A US Department of Energy article states that a leak of one drip of hot water per second can cost $1.00 per month. Making reasonable assumptions about drop size and unit cost of energy, determine if this claim is reasonable.
A “friend” asks you to construct the phase diagram for a new binary alloy of A and B. The clues are: (i) A and B are completely immiscible in each other and no solid solutions exist in the diagram, (ii) no stoichiometric compounds exist in the diagra..
