Free body diagram Draw the free body diagram (FBD) for this system. To draw the free body dagram, we assume that the bar is displaced a small amount in the positive direction of e. Important For the free body diagram, the forces also need to be labelledt You can draw the forces by cicking the application point (etters) and dragging or using the drop dovn with the draw button. If you drew them by clicking and dragging, dlick the force vector to label it from the dropdown menu above. Ithe label on the force doesnt appear on the diagram, you havent quite done itright and the question will keep getting graded as incomect even if you have the comect amows 600000 kz Equation of Motion Since the bar undergoes rotational motion, Nevtor's second law is written by writing a sum of moments around the pivot point (sum of moments cause rotational motion).

Question
Free body diagram Draw the free body diagram (FBD) for this system. To draw the free body diagram, we assume that the bar is displaced a small amount in the positive direction of 0. Important: For the free body diagram, the forces also need to be labelled! You can draw the forces by clicking the application point (letters) and dragging or using the drop down with the 'draw' button. If you drew them by clicking and dragging, click the force vector to label it from the dropdown menu above. If the label on the force doesn't appear on the diagram, you haven't quite done it right and the question will keep getting graded as incorrect even if you have the correct arrows. Fs k2 Fry Fg k1 Frx Equation of Motion Since the bar undergoes rotational motion, Newton's second law is written by writing a sum of moments around the pivot point (sum of moments cause rotational motion). Positive moments are those that are in the direction that tend to move things in what is defined as the positive direction for 0. In other words, a positive moment wants to send e in its positive direction (here clockwise) and a negative moment will send 0 in its negative direction. The equation of motion will look like Jo 0 (t) = Mo1+ Mo2 + Mo3 Here, Jo is the moment of inertia of the bar about the pivot point, O. and the Maj are the moments due to the two springs and gravity. The moment of inertia of the bar about the pivot point O is given by Jo Section Attempt 1 of 5 Verify
