Reading Question 17.13
Part A
The slender rod is pinned to a small massless roller A that slides freely along the slot. The rod is released from rest at ° = 0 and swings downward. Which of the following is the correct statement regarding the motion of the rod during the process? The slender rod is pinned to a small massless roller A that slides freely along the slot. The rod is released from rest at ° = 0 and swings downward. Which of the following is the correct statement regarding the motion of the rod during the process?
| a) The center of mass of the rod has a circular path |
| b) The maximum angular acceleration of the rod occurs when ° = 90° |
| c) The rotational equation of motion of the rod can be set up as MA=IA |
| d) The motion of the rod is rotation about a fixed axis |
| e) The center of mass of the rod moves along a straight line |
Solution
oprion (e) is correct.
tge center of mass of the rod moves along a straight line because net force on the rod in x direction is zero. Hence the center of mass will have velocity and acceleration in vertical direction only.
