MECH 242 – Principle of Work and Energy
18-5 (11th Edition) At the instant shown, link
AB has angular velocity ωAB. If each link is
considered a uniform slender bar with mass
density ρ, determine the total kinetic energy of
the system.

18-33 (11 Edition) A ball of mass m and radius r
is cast onto the horizontal surface such that it rolls
without slipping. Determine the minimum speed vG
of its mass center G so that it rolls completely
around the loop of radius R + r without leaving the
track.

18-53 (11th Edition) The slender rod AB of
weight W is attached to a spring BC which has
an unstretched length L. If the rod is released
from rest when θ = θ1 determine the angular
velocity of the rod the instant the spring
becomes unstretched.
