A beam with a length of 2 m and a mass of 10 kg supports a 50 kg box. The beam is connected to a wall by a hinge at its base and a horizontal wire. The wire is connected to the beam 1.5 m from the hinge and makes an angle θ of 35o to the beam. The goal is to find the tension in the wire and the horizontal and vertical components of the force exerted by the hinge on the board

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.

A house painter stands 3.00 m above the ground on a 5.00-m-long ladder that leans against the wall at a point 4.70 m above the ground. The painter weighs (6.60x10^2) N and the ladder weighs (1.900x10^2) N. Assuming no friction between the house and the upper end of the ladder, find the force of friction, in units of N, that the driveway exerts on the bottom of the ladder. Give your answer with three significant figures.
A non-uniform beam has a length of 4.74 m and a mass of 63.7 kg. The beam is resting horizontally on two supports. The first support is located 1.31 m from the left edge of the beam and applies an upward force of 199 N to the beam. The second support is located 1.86 m to the right of the first support. How much upward force is applied on the beam by the second support?
A beam rests on a fulcrum, 1.4 meters from one end. A weight of 495 kg is suspended from this end causing the beam to balance. If the weight of 495 is suspended on the opposite end of the beam, it is necessary to suspend a 2795 kg weight on the first end in order to effect an even balance. Use g = 9.81 m/s2.
A short cantilever beam is subjected to three forces. If α = 45°, determine the value of F in kN that will make the magnitude of the resultant of the three forces smallest as shown in the figure. Take F1 = 70 kN and F2 = 25 kN.
