A bar having a length of 125mm and a cross-sectional area of 400mm^2 is subjected to an axial force of 32kN. If the bar stretches 50 x10^-3mm. Determine the modulus of elasticity of the material. The material has a linear elastic behavior

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?

The power source in a certain welding setup generates 3500w that is transferred to the low carbon steel work with a heat transfer factor of 0.85. the melting factor in the operation is 0.45. a continuous fillet weld is to be made with a cross-sectional area of 23 mm2 determine the travel speed at which the welding can be accomplished.

Abrayton cycle operates with a regenerator on the air-standard with properties evaluated at 400 k. the tem- perature of the air entering the compressor is 350k while the temperature of the air exiting the compressor is 600 k. the temperature of the air entering the turbine is 1600 k. the overall cycle produced 600 kj/kg of net work out. assuming a regenerator effectiveness of 0.8, what is the temperature of the air before heat addition (combustion)? draw this process on a t - s diagram
