Task 1-
give illustrations and or descriptions of how the following forces would appear in structure under load.
•shear
•tension
•compression
•stress
•strain

task 2
predict the simple structural behaviour of the following -show using drawings:
•a steel portal frame overloaded at the bolted junction with the column •an overloaded and undersized concrete lintel spanning a window opening
•a strip foundation designed to take a load of 30 n/mm2, which is actually subjected to a load of 50 n/mm 2

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
