A 0.120kg, 50 cm long uniform bar has  small 0.055 mass glued to its left end and small 0.110 kg mass glued to the other end. The two small masses can be treated as point masses. You want to balanced this system horizontally on a fulcrum placed just under its center of gravity. How far from the left end should the fulcrum be placed?

A 3.72 kg iron box is suspended from a spring with a spring constant of k=18 N/m. The mass is pulled 0.35 m downward from its equilibrium position and allowed to oscillate. a) what will the angular velocity be for this iron box? b) with what period will the iron box oscillate?

A thin rod of mass 0.800 kg and length 0.700 m has a fixed pivot at one end.  The rod is held horizontally and released from rest.  The rod swings downward and back up again like a pendulum.  The rotational inertia of a thin rod rotating about one end is I=13ML2.  Disregard friction and air resistance.(a) Determine the initial angular acceleration of the rod just as it is released.(b) Determine the maximum angular speed of the rod as it swings back and forth.

A small ball is attached to one end of a spring that has an unstrained length of 0.222 m. The spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 4.52 m/s. The spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0102 m. By how much would the spring stretch if it were attached to the ceiling and the ball allowed to hang straight down, motionless? Number i eTextbook and Media Units +

Engineers are designing a system by which a falling mass m imparts kinetic energy to a rotating uniform drum to which it is attached by thin, very light wire wrapped around the rim of the drum (the figure (Figure 1)). There is no appreciable friction in the axle of the drum, and everything starts from rest. This system is being tested on earth, but it is to be used on Mars, where the acceleration due to gravity is 3.71 m/s2. In the earth tests, when m is set to 13.0 kg and allowed to fall through 5.00 m, it gives 300.0 J of kinetic energy to the drum. If the system is operated on Mars, through what distance would the 13.0-kg mass have to fall to give the same amount of kinetic energy to the drum? How fast would the 13.0-kg mass be moving on Mars just as the drum gained 300.0 J of kinetic energy?

A hollow cylinder of mass M1 and radius R1 rolls without slipping on the inside surface of another hollow cylinder of mass M2 and radius R2. Assume R1<<RZ. Both axes are horizontal, and the larger cylinder is free to rotate about its axis What is the angular velocity or frequency of small oscillations
