A post weighing 314. [N] and with height h has its lower end resting on a rough horizontal surface with μ = 0.214. The upper end is held by a rope fastened to the surface and making an angle of 0 = 25.0° with the post. A horizontal force F is applied at the midpoint of the post. What is the largest value F can have without causing the post to move?

An elastic rope is stretched between the tops of two identical posts. A man is to walk along the elastic rope. When the man is at the middle of the elastic rope, the tension in the elastic rope is 2220 N. Each half of the elastic rope makes an angle of 8.00with respect to the horizontal. Find the weight of the man.

A hungry bear weighing 730 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 5.00 m long, and it is supported by a wire at an angle of 0 = 60.0°. The basket weighs 80.0 N. Goodies Q (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File No file chosen This answer has not been graded yet. (b) When the bear is at x = 1.16 m, find the tension in the wire supporting the beam. N When the bear is at x = 1.16 m, find the components of the force exerted by the wall on the left end of the beam. (Assume the positive +x direction is to the right and the positiv direction is upward. Include the sign of the value in your answer.) Fx N N (c) If the wire can withstand a maximum tension of 775 N, what is the maximum distance the bear can walk before the wire breaks? m

The uniform boom shown below weighs 644 N, and the object hanging from its right end weighs 416 N. The boom is supported by a light cable and by a hinge at the wall. 45° | 20° 416 N Calculate the tension in the cable and the force by the hinge on the boom (both in N). (Enter the magnitudes.) tension in the cable force by the hinge N Does the force by the hinge act along the boom? (Assume this force acts along the boom if its direction in degrees above the horizontal is within 2% of the boom's angle above the horizontal.) O Yes O No
