1.The bucket of the front-end loader shown carries a 3200-lb load. The motion of the bucket is controlled by two identical mechanisms, only one of which is shown. Knowing that the mechanism shown supports one-half of the 3200-lb load, determine the force exerted (a) by cylinder CD, (b) by cylinder FH.
2.Flow occurs in a rectangular channel of 6 m width and has a specific energy of 3 m. Plot the q-curve. Determine from curve (a) critical depth (b) the maximum flow rate (c) the flow rate at a depth of 2.4 m and (d) the depths at which flow rate of 28.3 m^3/s may exist and the flow conditions at these depths.
