The boom DF of the jib crane and the column DE have a uniform weight of 50 lb/ft. If the hoist and load weigh 300 lb, determine the resultant internal loadings in the crane on cross sections through points A, B, and C. Equations of Equilibrium: For point A Equations of Equilibrium: For point B…
A planetary gear system also known as an Epicyclic gearing or planetary gearing. It consists of spur gears arranged in an epicyclic configuration. In this setup, a central gear, known as the sun gear, acts as the input and drives the system. Multiple “driven” gears, or planets, orbiting the sun gear within a gearbox. These planets mesh…
The Charpy impact test, also commonly referred to as the Charpy V-notch test by material scientists, serves as a standardized high-strain rate examination to quantify the energy absorbed by a material upon fracture. The absorbed energy functions as an indicator of the material’s notch toughness. Widely employed in various industries, this test is favored for…
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…
What is a combined loading? The objective of combined loading is to evaluate the stresses of a structural member when exposed to a variety of loads. Basically, these are forces that act on a structure in different ways, and understanding how they interact is crucial for creating buildings, bridges, automotive chassis and internal combustion engines….
