1 ME 240 Fall 2008 Problem Set 9: Due November 14 Problem 1: A constant force F is applied in the vertical direction to the symmetrical linkage starting from the rest position shown. Determine the angular velocity ω which the links acquire as they reach the position θ = 0 . Each link has a mass m 0 . The wheel is a solid circular disk of mass m and rolls on the horizontal surface without slipping. Problem 2: The masses of the bar and disk are 14 kg and 9 kg, respectively. The system is released from rest with the bar horizontal. Determine the angular velocity of the bar when it is vertical if the bar and disk is welded together at A .

2 Problem 3: The 1-slug homogenous cylindrical disk is given a clockwise angular velocity of 2 rad/s with the spring unstretched. The spring constant is k = 3 lb/ft. If the disk rolls, how far will its center move to the right? Problem 4: The system is in equilibrium in the position shown. The mass of the slender bar ABC is 6 kg, the mass of the slender bar
