Compute the tensile strength for the composite of given exercise assuming that all the fibers have the same tensile strength.
Exercise
Give an approximate value for the compressive strength of an Al-Boron composite with Vf = 0.4. Aluminum 2024 has E = 71GPa, Poisson = 0.334, G = 26.6 GP a, yield strength = 76 MP a, fatigue limit = 90 MP a, elongation = 22%. Boron fibers have E = 400 GP a, ultimate strength = 3.4 GP a, Poisson = 0.25.
Note that Boron fibers tend to be perfectly straight and that aluminum has a linear shear stress-strain plot before it yields.
What were the values of beta (β) for each stage? What 3 amplifier configurations were used? Explain the change in voltage gain when RE1 and RE2 were adjusted.
The plate is uniformly loaded from the bottom surface with a pressure load of 15 kN/m2. Elastic modulus is E = 210 x 109 N/m2 and Poisson's ratio is v = 0.33. Determine the von Mises distribution in the plate.
What minimum displayed green time must be provided to ensure that the queue in each cycle clears, and what is the total delay per cycle and delay per vehicle for this green time? (Assume D/D/1 queuing.)
The unit costs of electricity and natural gas are $0.092/kWh and $1.42/therm (1 therm = 105,500 kJ). Determine which system will have a lower energy cost.
