Question 1: For the loaded beam, as shown in the figure below, determine the magnitude of the counter weight Q for which the maximum absolute value of the bending moment is as small as possible. If this beam section is 150 mm x 200mm, determine the maximum bending stress. Neglect the weight of the beam.
Question 2: A beam of rectangular section 450 mm wide and 750 mm deep has a span of6 metres. The beam is subjected to a uniformly distributed load of 20 kN per metre run (including the self-weight of the beam) over the whole span. The beam is also subjected to a longitudinal axial compressive load of 1500 kN. Find the extreme fibre stresses at the middle sectionspan.
Compare the required material strength and cycle efficiency of this rankine cycle with a carnot cycle operating with the same TH (30 degrees celsius) and TL is (-5 degrees celsius) by calculating the percent change in max pressure and thermal efficie..
