Question

- A shop puts up a signboard of mass m hanging from the end of a rod of
length / and negligible mass, which is hinged to the shop wall at an axis 0.
The rod is held horizontal by means of a wire attached to its midpoint and to
the wall, a height h above the hinge (see Figure). If the wire will break when
its tension T reaches Tmax = 3mg, what is the minimum height hmia (in terms
of ) that the wire must be attached to the wall?

(Figure 1) shows a metal advertising sign of weight w suspended from the end of a horizontal rod of negligible mass and length L. The end of the rod with the sign is supported by a cable at an angle θ from the horizontal, and the other end is supported by a hinge at point P. Using the idea that there is zero net vertical force on the rod with the attached sign, find the tension in the cable. Using the idea that there is zero net horizontal force on the rod with the attached sign, find the horizontal component of the force exerted by the hinge.
A certain wire stretches 0.70 cm when outward forces with magnitude F are applied to each end. The same forces are applied to a wire of the same material but with four times the diameter and five times the length. The second wire stretches in cm: Answer must be according the correct signifcant numbers.

(b) 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 sup- ported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1200 N. (a) What value of D corresponds to that tension? (b) To prevent the cable from snapping, should D be increased or decreased from that value? D Cable Beam
Two uniform planks, each of mass m = 7.45 kg and length L = 2.51 m, are connected by a hinge at the top and by a chain of negligible mass attached at their centers, as shown in the figure. The assembly will stand upright, in the shape of an A, on a frictionless surface without collapsing. If the chain has the length 0.81 m, find each of the following: a) the absolute value of the tension in the chain, b) the absolute magnitude of the force on the hinge of each p lank
