DISCUSSION and HINTS
\n<\/strong><\/em><\/strong><\/em><\/p>\n

Recall the following f<\/em>our-step plan<\/em><\/span> outline in the lecture book and discussed in lecture:<\/p>\n

Step 1: FBDs<\/strong><\/em>
\nDraw a single free body diagram (FBD) of the bar and the particle.<\/p>\n

Step 2: Kinetics (Work\/energy)
\n<\/strong><\/em><\/p>\n

    \n
  • Looking at your FBD above, which forces, if any, do work that is not a part of the potential energy of the system? If there are none, then energy is conserved.<\/li>\n
  • Write down the individual contributions to the kinetic energy from the bar and particle, and add together for the total kinetic energy of the system.<\/li>\n
  • Define your gravitational datum line. Write down the individual contributions to potential energy from the bar, particle and spring, and add together for the total potential energy.<\/li>\n<\/ul>\n

    Step 3: Kinematics<\/strong><\/em>
    \nUse the following rigid body kinematics equation to relate the angular velocity of the bar to the velocity of the particle B at position 2:<\/p>\n

    v<\/strong>B<\/sub>= v<\/strong>G<\/sub> + \u03c9<\/strong>AB<\/sub> x r<\/strong>B\/G<\/sub><\/em><\/p>\n

    Step 4: Solve<\/strong><\/em>
    \nFrom your equations in Steps 2 and 3, solve for the angular velocity of the bar.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
