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.
