A cylindrical specimen of an aluminum alloy, has a Young's' Modulus of 59GPa, original length of 250mm, length at fracture of 254mm and a 0.2% yield stress of 287MPa. The specimen has a cross-sectional diameter of 15.2mm. If a load of 56KN is applied to it, a) Will the specimen experience elastic or plastic deformation?b) What is the strain when the load is applied? c) What will be the length of the specimen after the load is removed? d) The specimen was reloaded until fracture. If the % reduction in area after fracture was 40%, what is the minimum diameter of the specimen at fracture?
A rigid vessel of capacity 0.6 m3 contains dry saturated steam at 4.0 bar. The vessel is cooled until the pressure is reduced to 2.0 bar, Calculate; a) the mass of steam in the vessel.
You are designing a remote-area power supply based on a miniature wind turbine that is 20% efficient. Meteorological data indicates an average wind speed of 24 km/h at an air temperature of 10oC and pressure of 0.9 atm. The rotor has a diameter of..
design a process for the manufacture of 106 kg per year of mayonnaise. the shelf life of the product is expected to be
Friction between the piston and the cylinder wall can be neglected. For the air, determine the initial and final pressures, in kPa, and the work, in kJ.
the traveling crane consists of a 5-m-long beam having a uniform mass per unit length of 20kg/m. The chain hoist and its supported load exert a force of 8 kN on the beam when x=2m. draw the shear and moment diagrams for the beam.
How the tensile stress and compressive stress result in the moment about neutral axis when the beam fails
What is the acceleration of the truck if the coupling at C suddenly fails? The car wheels are free to roll. Neglect the mass of the wheels.
Calculate the static thrust of the turbojet engine having mass flow 88lbm/sec the ratio of air and fuel mass flowing into the turbojet is 50:1 and it's exhaust plane the velocity is 1640 ft/sec and pressure is same as ambient pressure?
Computer programs and other software (including Web Pages like this one). This includes graphics and icons and the like, which may also be "graphic works". OK, my work is on the list. How do I copyright it?
package is dropped from the plane which is flying with a constant horizontal velocity of vA = 150 ft/s at a height h = 1500 ft. Determine the radius of curvature of the path of the package just after it is released from plane at A.
The diffusion constant (Do) and activation energy (Q) of C in BCC Fe is 0.01 cm2/sec and 80kJ/mol respectively. In FCC Fe, the values are 0.21 cm2/sec and 148kJ/mol. At exactly 910oC these two phases can co-exist.
