good question, they forgot to include the weight of the block B in the free body diagram. In fact, they didn't include the weight of block A in its free body diagram, although that doesn't affect the solution. But the omission of block B weight was an apparent oversight that does affect the result.bigu01 said:
The picture is a top view. The mass of both blocks is relevant, but their weights are not.
Engineering Dynamics is a branch of physics that focuses on the study of motion and how forces affect the movement of objects. It is a fundamental aspect of engineering and is used to analyze and design various mechanical systems.
In Engineering Dynamics, weight is calculated by multiplying the mass of an object by the acceleration due to gravity (9.8 m/s^2). The unit of weight is typically measured in Newtons (N).
If weight is missing from a simple problem in Engineering Dynamics, it means that the force of gravity is not being considered. This could lead to inaccurate calculations and results. It is important to always include weight in any analysis involving forces and motion.
Sure, a simple problem in Engineering Dynamics could be calculating the acceleration of a ball rolling down a ramp with a given mass and angle of incline. The weight of the ball would be included in the calculations, along with other forces such as friction and normal force.
Engineering Dynamics has many real-life applications, including designing and analyzing various mechanical systems such as vehicles, bridges, and buildings. It is also used in sports, such as analyzing the motion of athletes and designing equipment like bicycles and helmets. Additionally, it is used in the development of aerospace technology and robotics.
