Consider 6.0 kg of austenite containing 0.45 wt% c and cooled to less than 727°c. a.what is the proeutectoid phase? b. how many kilograms each of total ferrite and cementite form? c. how many kilograms each of pearlite and proeutectoid phase form? d. schematically sketch and label the resulting microstructure.

What precautions should you take to prevent injuries when dealing with heavy loads?

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false

Determine the time of the day and month of the year at which the peak sensible cooling load occurs for a top floor, north-eastern corner room of an office building in durban for the following conditions: floor area: 8 x 8 x 3 m east and north walls: 115 mm face brick (outside), 20 mm air space, 115 mm ordinary brick (inside) with 15 mm plaster roof construction: suspended plasterboard ceiling, 450 mm air space, 150 mm concrete, 75mm screed, waterproofing no heat transfer across other surfaces window area 3x 1,5 m high in north wall only. ordinary glass with venetian blinds. lights and occupants : from 07: 00 to 18: 00 average light density: 25 w/m2 number of occupants : 5 seated, light office work room temperature 24°c
