Consider the sketch of the movable crane. Make a free-body diagram of the mobile crane. The wheels are 4 ft apart and the center of gravity is halfway between the wheels. Assume the ballast is an external force acting one foot behind the left axle and that the weight hanging off the crane at point B is also treated as an external force. Draw the free body diagram, label all the forces and dimensions. Be sure to include a coordinate axis.

Physics often focuses on simplifying complex phenomena to better understand and predict the natural world. This art of idealization is a cornerstone of mechanics, where we frequently encounter the concept of a “particle” or “point mass.” Within this context, the moment of inertia plays a crucial role, particularly in rotational dynamics. In thermodynamic equilibrium, all…
Determine the resultant internal normal force acting on the cross section through point A in each column. In (a), segment BC weighs 180 lb/ft and segment CD weighs 250 lb/ft. In (b), the column has a mass of 200 kg/m. Sample problems and notes are based on the following text book: Mechanics of Materials 8th…
What’s the difference between energy vs power? In the realm of physics and engineering, the concepts of energy and power are fundamental but often misunderstood. While they are closely related, they represent distinct aspects of physical systems. Energy is the ability to do work, while power is the rate at which work is done or…
The force acts on the gear tooth. Determine the resultant internal loadings on the root of thetooth, i.e., at the centroid point A of section a–a.

Buckling is a physical occurrence observed in slender structures, such as columns, beams, rods or panel; when it undergoes bending due to applied loads, leading to eventual buckling. This phenomenon can result in the complete failure of the structure. Buckling occurs when the applied load surpasses the structure’s buckling load, which represents the maximum load…
