ANSWER:
Problem 18-20
If P = 200 N and the 15-kg uniform slender rod starts from rest at u = 0, determine the rods angular velocity at the instant just before u = 45. A
Step by Step Solution
Step 1 of 3
kinetic energy
Since the slender rod starts from rest,the initial kinetic energy is zero. The kinetic energy at position 2 is
Where
