Question 2: Shear Stresses in Beams A built-up beam of box section is simply supported over a span of \( 3 \mathrm{~m} \) and carries a point load of \( 15 \mathrm{kN} \) at \( 1 \mathrm{~m} \) from the end. The plate is attached to the channel sections by rivets pitched at \( 100 \mathrm{~mm} \) intervals as shown in figure 2 . If the shear stress in the rivets must not exceed \( 50 \mathrm{MPa} \), 2.1 Determine a suitable rivet diameter (all dimensions in mm). Figure 2

A stream consisting of 45 m3 /min of moist air at 14?C, 1 atm, 80% relative humidity mixes adiabatically with a stream consisting of 95 m3 /min of moist air at 40?C, 1 atm, 40% relative humidity, giving a single mixed stream at 1 atm. Using the psychrometric chart, determine: a) the relative humidity and temperature, in ?C, of the exiting stream.
