An L-shaped rigid body ABC consists of two identical uniform slender rods, each of mass 40 kg and of length, L= 1.6 m welded together. The rigid body is pinned at its vertex B as shown, with the end C attached to a spring with a spring constant, 6 N/cm .
PART A - Determine the natural cycle frequency of the system.
PART B - If during the oscillatory motion the end A is observed to move with a speed of 0.12 m/s when AB is vertical, what is the maximum (linear) displacement of A (from the vertical)?
