A uniform beam of length L = 7.70 m and weight 4.75 ✕ 102 N is carried by two workers, Sam and Joe, as shown in the figure below. Determine the force that each person exerts on the beam.
A uniform bridge span weighs 50 103 N and is 40.0 m long. An automobile weighing 15 103N is parked with its center of gravity located 12.0 m from the right pier. Where is the center of mass of the bridge-automobile combination located as measured from the left pier?
A meter stick is pivoted at its 50cm mark but does not balance because of non-uniformities in its material that cause its center of gravity to be displaced from its geometrical center. However, when weights of 150g and 300g are placed at the 10cm and 75cm marks, respectively, balance is obtained. The weights are then interchanged, and balance is again obtained by shifting the pivot point to the 43cm mark. Find the mass of the meter stick and the location of its center of gravity.
