The torsional spring at A has a stiffness = 25 N.m/rad and is undeformed when the...
2. (40 points) A soccer ball tester consists of a 15-kg slender rod AB with a 1.1-kg sim- ulated foot located at A and a torsional spring located at pin B. The torsional spring has a spring constant of k 910 N.m/rad and is unstretched when AB is its lowest position. Fig. 2 depicts the simulation. The length of AB is 0.9 m, and you can assume that the foot ban be modcled as a particle, Knowing that the velocity...
2. In the mechanism shown, each of the two wheels has a mass of 30 kg and a centroidal radius of gyration of 100 mm. Each link OB has a mass of 10 kg and may be treated as a slender bar. The 7 - kg collar at B slides on the fixed vertical shaft with negligible friction. The spring has a stiffness k = 30 kN/m and is contacted by the bottom of the collar when the links reach...
show all work please find both AB and BC!! The assembly consists of two 25-kg bars which are pin connected. The bars are released from rest when 0 = 60°. The 8-kg disk at C has a radius of 0.5 m and rolls without slipping. (Figure 1) Figure 1 of 1 В 3 m 3 m o А C Determine the angular velocity of the bar AB at the instant 0 = 30°, measured clockwise. Express your answer in radians...
