To get up on the roof, a person (mass 70.0 kg) places a 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2 m from the bottom. The person is standing 3 m from the bottom. What are the magnitudes of the forces on the ladder at the top and bottom?

The figure below shows a bird feeder that weighs 100.1 N. The feeder is supported by a vertical wire, which is in turn tied to two wires, each of which is attached to a horizontal support. The left wire makes a 60° angle with the support, while the right wire makes a 30° angle. What is the tension in each wire (in N)
Concept Simulation 9.1 illustrates how the forces can vary in problems of this type. A hiker, who weighs 897 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4890 N, and rests on two concrete supports, one on each end. He stops 1/3 of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?
An object is subjected to three forces as shown in the figure. Assume F1 = 50.0 N and F2 = 95.0 N, what is T if the object is in static equilibrium? Enter a number with three significant digits.
The figure below shows a bird feeder that weighs 101.1 N. The feeder is supported by a vertical wire, which is in turn tied to two wires, each of which is attached to a horizontal support. The left wire makes a 60° angle with the support, while the right wire makes a 30° angle. What is the tension in each wire (in N)? A bird feeder is suspended from a vertical wire. The top of the wire is tied to two other wires. The left and right wires go up and to the left and up and to the right, respectively, from the connection point to a horizontal support. The left wire makes an angle of 60° with the support. The right wire makes an angle of 30° with the support. left wire Nright wire Nbottom wire N
A traffic light hangs from a 7.2-m long beam (AB) that is attached to a pole by a hinge (A), as shown. A horizontal (massless) cable (CD) supports the beam, making a 37° angle. The cable is attached to the pole 3.8 m above the hinge. The mass of the beam is 12 kg, and the mass of the traffic light is 22 kg. What is the tension in the cable? Also, the hinge exerts a force— with both horizontal and vertical components— on the beam. Find the magnitude of this force.
