A tightrope walker is walking between two buildings holding a pole with length ?=18.0 m,L=18.0 m, and mass ??=17.0 kg.mp=17.0 kg. The daredevil grips the pole with each hand a distance ?=0.560 md=0.560 m from the center of the pole. A bird of mass ??=515 gmb=515 g lands on the very end of the left‑hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force ?leftFleft and ?rightFright must the left and right hand exert to counteract the torque of the bird?
Consider a ladder with a painter climbing up it, as shown in Figure Q1.1. If the mass of the ladder is 12.0 kg, the mass of the painter is 55.0 kg, and the ladder begins to slip at its base when her feet are 70% of the way up the length of the ladder, determine: i) the force Fw, ii) the force Fc.

A horizontal, 2.00 m long, 3.00 kg uniform beam that lies along the east-west direction is acted on by two forces. At the east end of the beam, a 200 N force pushes downward. At the west end of the beam, a 200 N force pushed upward. What is the torque about the center of mass of the beam?
A tightrope walker is walking between two buildings holding a pole with length ?=15.5 m, and mass ??=19.5 kg. The daredevil grips the pole with each hand a distance ?=0.575 m from the center of the pole. A bird of mass ??=525 g lands on the very end of the left‑hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force ?left and ?right must the left and right hand exert to counteract the torque of the bird?
Which of the following statements ARE correct about equilibrium? 1. The sum of all forces should be zero 2. The sum of all acceleration should be zero 3. The sum of all torque should be zero 4. The sum of all momentum should be zero
How do you do this? A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see figure below). The beam is uniform, weighs 200 N, and is 6.00 m long, and it is supported by a wire at an angle of ? = 60.0°. The basket weighs 80.0 N. a) When the bear is at x = 1.00 m, find the tension (in N) in the wire supporting the beam and the components of the force exerted by the wall on the left end of the beam. b) If the wire can withstand a maximum tension of 875 N, what is the maximum distance (in m) the bear can walk before the wire breaks?
