1.If the 10-lb block passes point A on the smooth track with a speed of va = 5 ft/s determine the normal reaction on the block when it reaches point b.
2.Design a parshall flume to handle 24mgd in a 10ft wide channel at a downstream depth of 3 ft. If the channel floor is at elevation 65.7ft, what is the water elevation upstream of the flume? What is the flume crest elevation?
3.Using the orthotropic properties for AS4/3501-6 carbon/epoxy, write the compliance and the stiffness matrix under plane stress condition. E11=131.0 GPa, E22=23.3 GPa, v12=0.28, and G12=6.55 GPa.
4.For unidirectional carbon/epoxy tape at a 60% fiber volume fraction, calculate E11 and E22. Given Ef= 211 GPa and Em =10 GPa. Calculate the fiber weight fraction. Given pf=1.95 g/cm3 and pm =1.3 g/cm3.
