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 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.

a 400.0 n sign hangs from the end of a unifor strut. the strut is 4.0 m long and weighs 600.0 N. the strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut. find the tension in the supporting cable and the force of the hinge on the strout.

A 10 m long uniform board weighing 400 N is supported by ropes at each end. A worker weighing 900 N stands 3.0 m from the rope on the left. Determine the tension in the two ropes for static equilibrium.

The diagram shows a uniform 30 cm strut weighing 5 N supporting a 10 N weight 10 cm from the pivot. Find the tension in the cable attached to the wall. 10 cm 10 N 30°

A 7-m long beam of negligible mass is hanged horizontally and is supported at each end by vertical cables. The tension in the left cable is 300 N, and that in the right cable is 400 N. How far is the person sitting from the left cable?

A door has a height of 2.5 m along a y axis that extends vertically upward and a width of 1.12 m along an x axis that extends outward from the hinged edge of the door. A hinge 0.30 m from the top and a hinge 0.30 m from the bottom each support half the door's mass, which is 30 kg. In unit-vector notation, what are the forces on the door at (a) the top hinge and (b) the bottom hinge? (a) Number (b) Number i+ i Units Units

A scaffold of mass 67 kg and length 5.0 m is supported in a horizontal position by a vertical cable at each end. A window washer of mass 67 kg stands at a point 1.7 m from one end. What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable?

In the figure, a uniform beam of weight 440 N and length 2.3 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 1100 N. What value of D corresponds to that tension? Cable Вeam Number i Units
