Problem 18.18 The 5-kg slender bar is released from rest in the horizontal position shown. Determine the bar's counterclockwise angular acceleration (a) at the instant it is released, and (b) at the instant when it has rotated 45°. Solution: (a) The free-body diagram is shown. $\sum M_O: mg\frac{L}{2} = \frac{1}{3}mL^2\alpha$ $\alpha = \frac{3g}{2L} = \frac{3(9.81 m/s^2)}{2(1.2 m)} = 12.3 rad/s^2.$ $\alpha = 12.3 rad/s^2.$ (b) The free-body diagram is shown. $\sum M_O: mg\frac{L}{2}cos45^\circ = \frac{1}{3}mL^2\alpha$ $\alpha = \frac{3g}{2L}cos45^\circ = \frac{3(9.81 m/s^2)}{2(1.2 m)}cos45^\circ$ $\alpha = 8.67 rad/s^2.$

Create an office script that splits a single row of User information by using the formulas we generated for the previous steps. a) Make sure the active cell is the next entry to be split. If you followed along with the instructions, row 5 will be the next to be worked on, your sheet should look like this: COSC1702 - Project #4 Project #4/Ver 2 b) We are going to be recording this script relative to cell B5, so make sure you have that cell selected BEFORE clicking record actions. c) Click on the Record Actions button in the Automate tab. d) When the Record script dialog box appears again, make sure you are set to relative mode. Move across the row to column F (you should be in F5) and copy the formula entered in F4 into F5. i. Then move one column to the right (now in column G5) and copy the formula entered in G4 into G5. ii. Then move to the Name Column B (now in column B5) and copy the formula entered in B4 into B5. iii. Then move to the City Born Column C (now in column C5) and copy the formula entered in C4 into C5.
