Chapter 12, Problem 40P
Figure 12-54a shows a horizontal uniform beam of mass mb and length L that is supported on the left by a hinge attached to a wall and on the right by a cable at angle θ with the horizontal. A package of mass mp is positioned on the beam at a distance x from the left end. The total mass is mb + mp = 61.22 kg. Figure 12-54b gives the tension T in the cable as a function of the package’s position given as a fraction x/L of the beam length. The scale of the T axis is set by Ta = 500 N and Tb = 700 N. Evaluate (a) angle θ, (b) massmb, and (c) mass mp.

A rod of length L with non-uniform mass distribution is hinged horizontally to a vertical wall from
one end. The rod is supported by a rope from the other end as shown in the figure such that the
rope makes an angle of 30° with the horizontal. The linear mass density (mass per unit of length)
of the rod is A(x)=8Cx/L where x is the distance from the hinge (x < L) and C is a constant.
The unit of C is kg. The distance between point mass m and the hinge is L/2.
