The spring is uncompressed when the uniform slender bar is in the vertical position shown. Determine the initial angular acceleration a of the bar when it is released from rest in a position where the bar has been rotated clockwise 33° from the position shown. Neglect any sag of the spring, whose mass is negligible. The angular acceleration is positive if counterclockwise and negative if clockwise. The mass m of the bar is 18 kg, the length / is 305...

A particle of mass m and of negligible dimensions is fixed to the end of a uniform slender bar of mass m and length L. The compound particle-bar is released from rest in the vertical position (O=0) and given a slight nudge such that the center of its square end pivots about the corner o. The bar is observed to slip when the angle reaches the critical value 0=6c. YOUR CHOICE: Use the following parameter values: m=0.25kg, L=0.75 m &...
