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 N, and is 7.00 m long, and it is supported by a wire at an angle of θ = 60.0°. The basket weighs 80.0 N. A horizontal plank is attached at the left end to a vertical wall. A rod with a pulley at the right end extends a distance x horizontally to the right from the wall above the plank. A cable connected to the wall just above the rod goes around the pulley then down and right to the end of the plank, making an acute angle θ with the plank. A basket of goodies hangs down from the right end of the plank and a bear stands on the plank below the rod a distance x from the wall. (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) This answer has not been graded yet. (b) When the bear is at x = 1.10 m, find the tension in the wire supporting the beam. N When the bear is at x = 1.10 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 positive +y direction is upward. Include the sign of the value in your answer.) Fx = N Fy = N (c) If the wire can withstand a maximum tension of 875 N, what is the maximum distance the bear can walk before the wire breaks? m
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
