1. The table below shows the relevant task data for a certain project, with durations given in days. a. Draw a fully analyzed network diagram for the project showing all activity times, find the project duration, develop the activities boundary timetable, and identify the critical path. b. Assuming each task starts as soon as possible, construct the Gantt chart and corresponding resource loading diagram for the project. c. Construct a second resource loading diagram showing how the timing of individual tasks could be rearranged to reduce the fluctuation in worker demand, without changing overall project duration. d. If only 7 workers are available, how would you assign workers to tasks to ensure that the project can be completed without violating the resource limit? The project duration may be extended in this case if necessary. (15 points) Task Predecessor Duration Workers A - 3 5 B - 2 2 C - 4 3 D B,C 3 2 E A 5 3 F D 3 4

6. The trajectory of a projectile is given by: x(t) = v_ocos(?)t; y(t) = v_osin(?)t - 0.5gt² (2) where x is the distance down range for the projectile (ft), y is the height of the projectile above the launching point (ft), t is the time (s), v_o is the initial velocity (500 ft/s), ? is the angle with the horizontal when the projectile is launched (35°) and g is the gravitational constant (32.2 ft/s²). Use the equation for y(t) to determine the time when the projectile hits the ground (y(t) = 0 assuming level ground) and use this time to make the following plots: 6.1. Develop a plot of x(t) versus t. 6.2. Develop a plot of y(t) versus t. 6.3. Develop a plot of y(t) versus x(t). Each plot should have a proper title, axes labels and axes numbers.
