11. [013 Points] DETAILS PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER Suppose a 920 kg car is on the bridge in the gure below with its center of mass halfway between the hinges and the cable attachments. (The bridge is supported by the cables and hinges only.) The mass of the bridge is 2300 kg. J- . .-' (a) Find the force in the cables. (Enter your answer in N.) _x~ (b) Find the direction (in degrees counterclockwise from the dotted line) and magnitude (in N) of the force exerted by the hinges on the bridge. magnitude 71001 x N direction 2 counterclockwise from the dotted line T Use the hinge as your pivot point. Make sure you remember to include the hinge force acting to push the rod away from the wall and upwards (so it has an x- and a y-component). You'll need all three equilibrium equations to get the answers. Additional Materials L3 Reading Submit
