A uniform beam 3.7 mm long and weighing 3000 NN carries a 3000 NN weight 1.50 mm from the far end, as shown in (Figure 1). It is supported horizontally by a hinge at the wall and a metal wire at the far end. a)How strong does the wire have to be? That is, what is the minimum tension it must be able to support without breaking? b)What are the horizontal component of the force that the hinge exerts on the beam? c)What are the vertical component of the force that the hinge exerts on the beam?
Hi, I am in physics I and I'm trying to understand this word problem. It saids that a 6.0-m uniform board is supported by two sawhorses 4.0m apart. A 32kg child walks on the board to 1.4 m beyond the right support when the board start to tip. a.) Find the mass of the board b.) Then he walks back 0.40m and stands still. Find the forces exerted by the supports at this time. (use the mass found in part a). Please be detailed of how this works. Its a harder problem for me to understand. Thank you!
A uniform beam is 4.38 m long and has a mass of 69.1 kg. In the figure, the beam is supported in a horizontal position by a hinge and a cable, with angle θ = 60.2°.

Consider a rigid steel beam of length L = 11.5 m and mass mb = 405 kg resting on two supports, one at each end. A worker of mass mw = 76 kg sits on the beam at a distance x from support A. Refer to the figure. a)When the worker sits at a distance x = 4.5 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 = 2180 N. At what distance x, in meters, from support A is the worker sitting now?
Tweedledum and Tweedledee are carrying a uniform wooden board that is L = 3.00 m long and has a weight of www = 160 N.

The large quadriceps muscle in the upper leg terminates at its lower end in a tendon attached to the upper end of the tibia (see Figure a). The forces on the lower leg when the leg is extended are modeled as in Figure b, where T is the force of tension in the tendon, w is the force of gravity acting on the lower leg, and F is the force of gravity acting on the foot. Find T when the tendon is at an angle of 25.0° with the tibia, assuming that w = 29.0 N, F = 12.3 N, and the leg is extended at an angle ? of 40.0° with the vertical. Assume that the center of gravity of the lower leg is at its center and that the tendon attaches to the lower leg at a point one-fifth of the way down the leg. (Give the magnitude.)
