Figure 12-52a shows a horizontal uniform beam of mass m_b 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 ? with the horizontal. A package of mass m_p is positioned on the beam at a distance x from the left end. The total mass is m_b + m_p = 60.2 kg. Figure 12-52b 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 ?, (b) mass m_b, and (c) mass m_p.
