    Forces surrounding Car on a Bridge

    Oh ok! That makes sense, however the bridge length is only given to be AB. So that would mean, if A was the rotation point, that A=0 and therefore B=7500AB right?

    How Does Fred the Monkey's Descent Affect the Cylinder's Rotation?

    Don't you have to keep more in mind than just the torque and tension? Such as gravity? I'm not sure how those would fit together.

    Forces surrounding Car on a Bridge

    I didn't know what a moment was so I read the explanation but doesn't that mean that the force around point B would just be a normal force of 7500 because the object is static? But that isn't the right answer.

    Forces surrounding Car on a Bridge

    Homework Statement An W = 7500 N automobile is stalled one-quarter of the way across a bridge (see Fig. P77). Compute the additional reaction forces at supports A and B due to the presence of the car. Take the length of the bridge to be AB. Homework Equations The Attempt at a...
