Correct answer 9. [20 pts] A 1.50 m long uniform plank is fixed to a vertical wall with a frictionless hinge. Some Dacron fishing line is attached to the plank 0.615 m away from the hinge making an angle of & = 60.0 [see the figure below). The fishing line can hold up to 222 N before breaking. a. Draw the Extended/Torque Free-Body Diagram you will use to solve parts b and c. b. What is the maximum mass (in kg) that the plank can have and still be supported by the fishing line? Using the maximum mass found in part b, find the horizontal and vertical components of the force the c. hinge exerts on the plank (magnitude and direction!l)
