Consider a rigid steel beam of length L = 14 m and mass mb = 405 kg resting on two supports, one at each end. A worker of mass mw = 68 kg sits on the beam at a distance x from support A. Refer to the figure, though note that it is not drawn to scale.
a. When the worker sits at a distance x = 7.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures.
b. The force exerted on the beam by support A is measured and found to be FA = 2240 N. At what distance x, in meters, from support A is the worker sitting now?
In the figure below, a uniform beam of weight 500 N and length 3.0 m is suspended
horizontally. On the left it is hinged to a wall; on the right it is supported by a cable
bolted to the wall at distance D above the beam.
The least tension that will snap the cable is 1200N.
(a) What value of D corresponds to that tension?
(b) To prevent the cable from snapping, should D
Cable
be increased or decreased from that value?
Beam
A uniform 400 N beam of length L = 4 m is supporting
a 2000 N box as shown. Find the tension in the tie rope
and the force F exerted by the hinge at point P.
P.S. You don't have to answer the whole question. Please just explain how to solve the tension.

- A car is stuck in the mud. A tow truck pulls on the car with the arrangement shown. The tow cable is under a tension of 2 500 N and pulls downward and to the left on the pin at its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut; that is, each is a bar whose weight is small compared to the forces it exerts and which exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tensionor compression in each strut. Proceed as follows. Make a guess as to which way (pushing or pulling) each force acts on the top pin. Draw a free-body diagram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations. From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means that the direction should be reversed,…arrow_forwardA 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.
