Sample Problem

Shows a safe. of mass M = 430 kg. hanging by a rope from a boom with dimensions a = 1.9 m and b = 2.5 m. The boom consists of a hinged beam and a horizontal cable that connects the beam to a wall.

(a) What is the tension in the cable? In other words, what is the magnitude of the force f.. on the beam from the cable?

SOLUTION: The system hers: is the beam alone. and the forces on it are shown in the free-body diagram . The force from the cable .The gravitational.

CHECKPOINT 4: In the figure, a stationary 5 kg rod AC is held against a wall by a rope and friction between rod and wall. The uniform rod is I m long, and angel. (a) If you are to find the magnitude of the force f on the rod from the rope with a single equation, at what labeled, point should a rotational axis be placed? With that choice of axis and counterclockwise torques .
