4. A pry bar of length 0.6 m is used to slightly lift one side of a 120-kg rectangular cabinet of side L as shown in Figure 7. The center of gravity of the cabinet is a distance L/3 from its rear side. What force P has to be applied to the end of the pry bar and perpendicular to it? L/3 CG L 4 cm 0.6 m 30°

A rigid beam of length 490 cm and uniform mass 89 kg suspends two masses on light strings at each end as shown in the figure. If mass m₁ = 33 kg and m₂ = 49 kg, at what distance x should the pivot be placed such that the beam is balanced?

In the figure, a nonuniform bar is suspended at rest in a horizontal position by two massless cords as shown in the figure here. One cord makes the angle 0 = 31.1° with the vertical; the other makes the angle p = 58.9° with the vertical. If the length L of the bar is 5.9 m, compute the distance x from the left end of the bar to its center of mass. L com

A rod is attached to a pivot on the wall at one end and suspended horizontally at the other end by a wire as shown in Figure. The wire makes 30° to the rod. The rod has mass M = 2.0 kg and length L-4.0 m. At the end suspended by the wire, an object of mass m - 1.0 kg is hung by a wire. Find the tensin T on the wire that suspends the rod in N. wire R 30° L rod pivot m

A sign for a pizza restaurant hangs from a 2.60-m long rod extended out from a building. A cable, attached to the building, is attached to the rod at a point that is 2.10 m from the hidge. (See the figure.)The mass of the rod is 5.90 kg. The mass of the sign is 9.40 kg. The angle between the building and the rod is 74.0 degrees. The angle between the cable and the horizontal is 31.0 degrees.What is the torque on the rod due to the weight of the rod alone? [Take the axis to be at the hinge.]
